Suppose a retailer claims that the average wait time for a customer on its support line is 173 seconds. A random sample of 56 customers had an average wait time of 164 seconds. Assume the population standard deviation for wait time is 50 seconds. Using a 95​% confidence​ interval, does this sample support the​ retailer's claim?

Using a 95​% confidence​ interval, does this sample support the​ retailer's claim? Select the correct choice​ below, and fill in the answer boxes to complete your choice. ​(Round to two decimal places as​ needed.)

A. No​, because the​ retailer's claim is not between the lower limit of nothing seconds and the upper limit of nothing seconds for the mean wait time.

B. Yes​, because the​ retailer's claim is nothing between the lower limit of nothing seconds and the upper limit of nothing seconds for the mean wait time.

3. The percentage discount offered by suppliers if the customer or buyer pays early is known as the _____________discount.

4. The average length of time between the point in which a firm originally receives its inventory and the point at which it receives the cash from selling its product(s) is known as the __________cycle. Meaning of Cash Cycle is the average length of time between when a firm originally purchases its inventory and when it receives the cash back from selling its product.

17. The number of days a buyer has to take advantage of the cash discount provided by its suppliers is known as the ____________period.

18. A measure of the cash cycle calculated as the sum of a firm's inventory days and accounts receivable days, minus its accounts payable days is known as the ____________ cycle.

35. The total length of time during which suppliers extend credit to their customers (or buyers) is know as the ___________period.

For each problem, perform the following steps. Assume that all variables are normally or approximately normally distributed.

1. State the hypothesis and identify the claim.

2. Find the critical value(s).

3. Compute the test value.

4. Make the decision.

5. Summarize the results.

4. According to the 2005-2006 National Pet Owners Survey, only 16% of pet dogs were adopted from an animal shelter and 15% of pet cats were adopted. To test this difference in proportions of adopted pets, a survey was taken in a local region. Is there sufficient evidence to conclude that there is a difference in proportions? Use α = 0.05. [4]

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.

1. Determine whether the difference in proportions is significant at the 0.05 level.

2. Repeat the problem with the same proportions but a sample size of 5000 instead of

   500.

3. 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 ?

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.

1. On June 27, 2018, the bookkeeper received $20,000 for a shipment to be sent on July 8, 2018. The bookkeeper debited Cash and credited Product Revenue on June 27.

2. The company performed a physical inventory count on June 30, 2018 and determined that the inventory value on hand was $25,000.

3. The unadjusted balance in the Prepaid Expense account includes prepayment on an advertising contract. The balance in Prepaid Expenses as June 30, 2018 should include:

1. Advertising - January 1 - December 31, 2018 annual contract, original contract amount was $60,000.
2. Rent - July 2018 payment of $2,000. When the bookkeeper paid this on June 29th, he debited Rent Expense and credited Cash.

4. Depreciation expense for the 6 months ended June 30, 2018 should be $10,000.

5. On January 1, 2018, the company borrowed $60,000 at a 5% annual rate. The loan is to be paid back to the bank annually on December 31st in three equal installments beginning December 31, 2018. Each payment will include the interest incurred for that year. The interest for the year should be expensed evenly throughout the year. (Hint: there are two adjustments to be made)

6. Income tax expense must be re-calculated after all adjustments have been recorded. The income tax rate is 35%.

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.

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

• Review the individual difference factors and social factors that contribute to achievement gaps (e.g., the math gap) between boys and girls and men and women.
• Identify one achievement gap that you have experienced or witnessed, either in the classroom or in the workplace. Then, identify at least one individual difference factor and one social factor that appear to contribute to this achievement gap. Consider how this achievement gap influences both the individual and society as a whole.

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

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
