Weight Loss in Men Many polls have asked people whether they are trying to lose weight. A Gallup poll in November 2008 showed that 22% of men said they were seriously trying to lose weight. In 2006, 24% of men (with the same average weight of 194 pounds as the men polled in 2008) said they were seriously trying to lose weight. Assume that both samples contained 500 men.
Determine whether the difference in proportions is significant at the 0.05 level.
Repeat the problem with the same proportions but a sample size of 5000 instead of
500.
Comment on the different p-values and conclusions with different sample sizes.

According to Rindler the geodetic effect can be considered as consisting of Thomas precession combined with the effect of moving through curved space.
Wolfgang Rindler (2006) Relativity: special, general, and cosmological (2nd Ed.) p234
However according to Misner, Thorne, and Wheeler, Gravitation, p. 1118, Thomas precession does not come into play for a freely moving satellite.
See: http://en.wikipedia.org/wiki/Talk:Geodetic_effect
I think that although a freely moving satellite doesn't feel gravity, it's relation to an observer is still subject to lorentz transformations and hence Thomas precesssion.
So who is right ? Rindler or Misner, Thorne, and Wheeler ?

Achievement gaps, or differences in performance, exist between boys and girls and men and women. These gaps may relate to athletic performance, career choice or success, academic achievement, or general psychological measures such as cognitive abilities. The question that contemporary research seeks to answer is why these gaps exist and what can be done to lessen or eliminate them. One category of variables that can affect achievement is individual differences such as self-concept or attitudes. For instance, girls or boys may exhibit less self-confidence in academic domains that have been traditionally associated with success by the other sex. It is important to note that although these differences appear to arise internally, from the self, the environment (e.g., messages individuals receive about gender stereotypes or experiences they have) also influences individual differences. Biological and environmental influences do not exist in isolation from one another. Strong evidence exists for the influence of social factors, especially input from parents and educators, in affecting performance and interest in various domains, which can have a widespread and long-lasting influence.
A difficulty in studying achievement gaps is that sex and gender are not the only identities that affect achievement. Economic status, ethnicity, culture, and other facets of identity may interface with sex and gender to create complex dynamics. You may notice in your text that many studies report gender achievement gaps in certain areas for one ethnic group but not another, or in one age group but not another.
For this Discussion, you will examine one gender achievement gap in depth by explaining the factors that influence it and how it affects individuals and societies. In your response posts, you will share strategies that could be used to mitigate the gaps your colleagues discussed.
To prepare
By Day 4
Post a description of the achievement gap and the influencing factors (individual and social) you identified and how they affect you personally. Explain how this achievement gap is supported by gender stereotyping or gender-related socialization. Finally, explain how these achievement gaps may have implications for both individuals and society as a whole

You have been hired by DDB Corporation to prepare the financial statements. The company has provided you with the following information necessary to record adjustments required to show accurate financial statements.
Requirements:
(1) Show trial balance spreadsheet. Reference each adjustments with the letter used above.
(2) show properly formatted income statement and balance sheet based on the adjusted balances from your trial balance spreadsheet. List each account separately in your statements (for example, do not have one amount on your income statement labeled "operating expenses"). . Per share information is not given so you do not need to include earnings per share on your income statement.
(3) Calculate the net profit margin and current ratio for the financial statements.
(4) Show memo to the shareholders reporting the company's financial results for the six months ended June 30, 2018. Include a brief explanation of your ratio analysis results from requirement (3). Also, the company is considering the purchase of a $75,000 piece of equipment. One plan to acquire the equipment calls for a $50,000 cash payment with the remainder financed on a six-month loan. Assuming all account balances other than those accounts affect by the equipment purchase remain the same, include an explanation of the effect of this financing arrangement on the company's current ratio. Ignore interest expense on the new loan.

Junior Sayou, a financial analyst for Chargers Products, a manufacturer of stadium benches, must evaluate the risk and return of two assets, X and Y. The firm is considering adding these assets to its diversified asset portfolio. To assess the return and risk of each asset, Junior gathered data on the annual cash flow and beginning-and end-of-year values of each asset over the immediately preceding 10 years, 2006-2015. These data are summarized in the attached table. Junior’s investigation suggests that both assets, on average, will tend to perform in the future just as they have during the past 10 years. He, therefore, believes that the expected annual return can be estimated by finding the average annual return for each asset over the past 10 years. Junior believes that each asset’s risk can be assessed in two ways: in isolation and as part of the firm’s diversified portfolio of assets. The risk of the assets in isolation can be found by using the standard deviation and coefficient of variation of returns over the past 10 years. The capital asset pricing model (CAPM) can be used to assess the asset’s risk as part of the firm’s portfolio of assets. Applying some sophisticated quantitative techniques, Junior estimated betas for assets X and Y of 1.60 and 1.10, respectively. In addition he found that the risk-free rate is currently 7.0% and that the market return is 10.0%.
Calculate:
1) Expected return on a portfolio XY
2) Risk on a portfolio XY
Weight of each asset is 50%. Average annual return: asset X: 11.74% asset Y: 11.14% Standard deviation: asset X: 8.9 asset Y: 2.78

Maggie bought a house which was quite a dump in 1989 for $75,000. She fixed it up with paint and wallpaper but in 1996 she did a major renovation which cost $50,000. In 1993, she bought a dump of a cottage for $35,000 because it was both on a lake and near some good cross-country ski trails. She winterized it immediately for $10,000. Over time, the dumpy cottage has become quite attractive with the addition of a new roof, siding, windows and doors all of which cost $15,000 in 1995. In addition, she is fond of landscaping and has created quite a beautiful garden. I might add that Maggie has only $40,000 in RRSPs since she prefers to sink her money into her living space.
In July 2006, Maggie lost her job and received $60,000 in severance pay. She put as much as she could into her RRSP (included in the $40,000 above) and put the rest in GICs to help finance her plan. Maggie had been taking courses for several years to become a Master Gardener.
When she lost her job, she decided to live out her dream of having a gardening business where she would design gardens for others with cottages near her and maintain them if they needed it because they mostly come to their cottages on the weekend to relax. In the winter, she will keep the lanes clear (with her snow blower) and check up on the cottages now and again. She gave her corporate clothes to her friend Kate with the proviso that she could stay with her when she comes to the City (which won’t be often because she is very fed up).
When she lost her job, she immediately started renting out the house for $1,600 a month plus utilities. She still has to pay the $2,400 a year taxes and maintenance but figures the house will be her retirement fund. When she started renting out the house, it immediately ceased to be her principal residence – her cottage is now her principal residence. In July 2006, her house was worth $300,000 and the cottage is worth $140,000.
Questions:
a. Maggie’s house increases in value at about 3% a year from 2006 and she sells it in 2017. How much is her taxable capital gain on the house ignoring real estate commissions?
b. Maggie’s cottage also increases 3% a year in value. If she also sells it in 2017 in order to buy a bed and breakfast, how much is her taxable capital gain?

A airline wishes to estimate the mean number of seats that are empty on flights that use 737-airplanes. There are 189 seats on a plane. To do so, the airline randomly picks n=35 flights. For each flight, the number of empty seats is counted. The data are given below.
38, 42, 44, 42, 40, 45, 37, 31, 33, 36, 35, 39, 37, 37, 43, 38, 41, 27, 33, 35, 37, 46, 32, 35, 35, 42, 37, 41, 29, 40, 44, 34, 34, 41, 29
(a) Find the mean and the standard deviation of this sample. Use at least three decimal places in each answer.
(b) To construct a confidence interval for the mean number using the T distribution for unoccupied seats on all flights, what condition must you hold?
A. That the number of unoccupied seats are normally distributed.
B. The sample size is sufficiently large for the Central Limit Theorem to provide a valid approximation.
C. The number of unoccupied seats can be modeled by the Binomial distribution.
D. The number of unoccupied seats are not normally distributed.
(c) Find a 90% Student T confidence interval for μ, the mean number of empty seats on this airline's flights. Use at least three decimal points for your lower and upper bounds.
Lower Bound =

One source of new-product ideas is competitors. Steven Fischer recently joined Frankie and Alex Specialty Products as a brand manager. His new boss told him, “We don’t have a budget for new-product development. We just monitor our competitors’ new-product introductions and offer knockoffs of any that look like they will be successful.” Is this practice ethical? Does the AMA Statement of Ethics address this issue?
Go to the American Marketing Association’s website and review the statement. Then discuss what the AMA Statement of Ethics contains that relates to knock-off products.
HERE IS THE ARTICLE:
Codes of Conduct | AMA Statement of Ethics
Statement of Ethics
Preamble
The American Marketing Association commits itself to promoting the highest standard of professional ethical norms and values for its members (practitioners, academics and students). Norms are established standards of conduct that are expected and maintained by society and/or professional organizations. Values represent the collective conception of what communities find desirable, important and morally proper. Values also serve as the criteria for evaluating our own personal actions and the actions of others. As marketers, we recognize that we not only serve our organizations but also act as stewards of society in creating, facilitating and executing the transactions that are part of the greater economy. In this role, marketers are expected to embrace the highest professional ethical norms and the ethical values implied by our responsibility toward multiple stakeholders (e.g., customers, employees, investors, peers, channel members, regulators and the host community).
Ethical Norms
As Marketers, we must:
Ethical Values
Honesty – to be forthright in dealings with customers and stakeholders. To this end, we will:
Responsibility – to accept the consequences of our marketing decisions and strategies. To this end, we will:
Fairness – to balance justly the needs of the buyer with the interests of the seller. To this end, we will:
Respect – to acknowledge the basic human dignity of all stakeholders. To this end, we will:
Transparency – to create a spirit of openness in marketing operations. To this end, we will:
Citizenship – to fulfill the economic, legal, philanthropic and societal responsibilities that serve stakeholders. To this end, we will:
Implementation
We expect AMA members to be courageous and proactive in leading and/or aiding their organizations in the fulfillment of the explicit and implicit promises made to those stakeholders. We recognize that every industry sector and marketing sub-discipline (e.g., marketing research, digital marketing, direct marketing, and advertising) has its own specific ethical issues that require policies and commentary. An array of such codes can be accessed through links on the AMA Web site. Consistent with the principle of subsidiarity (solving issues at the level where the expertise resides), we encourage all such groups to develop and/or refine their industry and discipline-specific codes of ethics to supplement these guiding ethical norms and values.
Sexual or Personal Harassment Policy
Sexual harassment is any conduct, comment, gesture or contact of a sexual nature that is unwanted or unwelcome by any individual, or that might reasonably be perceived by that individual as placing a condition of a sexual nature on any AMA-related activity.
Personal harassment is any conduct, verbal or physical, that is discriminatory in nature, based upon another person’s race, color, ancestry, place of origin, political beliefs, religion, marital status, physical or mental disability, sex, age or sexual orientation. Personal harassment includes but is not limited to discriminatory or other behavior, directed at an individual, that is unwanted or unwelcome and causes substantial distress in that individual and serves no legitimate AMA-related purpose.
The AMA does not tolerate sexual or personal harassment, including at its events. Sexual or personal harassment in any form is strictly prohibited and may be grounds for suspension or termination as an officer, director or member of AMA.
