An investor purchased 300 shares of ABC Company when it IPO’d at $30 per share. Two years later, the company executed a 3 for 2 stock split when the shares were trading at $45. One year after that, the investor sold 200 shares at $40. What is her profit on the sale?

a$2,000

b$2,500

c$3,000

d$4,000

Compute the image location and magnification of an object 40 cm from a doublet thin lens
combination having focal lengths f1 = +20 cm and f2 = −60 cm, given that the second
lens is positioned 12 cm behind the front one. If the object is two centimeters high determine
the size and the type of the image. Make a sketch of appropriate rays that support your
findings.

To determine whether patients are responsive to a particular chemotherapeutic agent, colonies of cells are grown from each patient and then treated with the agent in question. To compare two agents, two samples are prepared simultaneously, from each patient, one sample treated with each drug, and the number of colonies in the culture counted. The data listed below show the results of such an experiment. On each line, the colony counts the resulting from treatment 1 and treatment 2 are given for a particular patient.

Do the two treatments have the same effect on colony formation? Use two techniques, one parametric and one nonparametric, to answer this question. This is a paired data problem.

Summarize all results giving hypotheses, significance level, tests performed, statistics, and conclusions.

Has Gold Lost Its Luster?

In 2011, when the Gallup organization polled investors, 34% rated gold the best long-term investment. In April of 2013 Gallup surveyed a random sample of U.S. adults. Respondents were asked to select the best long-term investment from a list of possibilities. Only 241 of the 1005 respondents chose gold as the best long-term investment. By contrast, only 91 chose bonds.

1. Compute the standard error for each sample proportion. Compute and describe a 95% confidence interval in the context of the question.
2. Do you think opinions about the value of gold as a long-term investment have really changed from the old 34% favorability rate, or do you think this is just sample variability? Explain.
3. Suppose we want to increase the margin of error to 3%, what is the necessary sample size?
4. Based on the sample size obtained in part c, suppose 120 respondents chose gold as the best long-term investment. Compute the standard error for choosing gold as the best long-term investment. Compute and describe a 95% confidence interval in the context of the question.
5. Based on the results of part d, do you think opinions about the value of gold as a long-term investment have really changed from the old 34% favorability rate, or do you think this is just sample variability? Explain.

Imagine that you are preparing taxes for a local tax service provider. A married couple named Judy and Walter Townson has come to you to seeking assistance with their federal income taxes. During your meeting with the Townsons, you gather the following information:

-they are both 55 years of age
-They have two daughters and one son. One daughter (25) is married with children. One daughter (20) is living at home and attending college. Their son (16) is a junior in high school.
-They are currently paying for their college-student daughter to attend school full time.
- Judy is employed as a teacher and makes $60,000 a year. She used $500 of her personal funds to purchase books and other supplies for her classroom.
-Walter is employed as a CPA and makes $100,000 a year
- They provided you a 1099-INT which reported $4,500 in the interest of which $500 was saving bonds interest
- They offered you a 1099-DV which said $300 in dividends
-They received a state tax refund last year of $385
- They provided you a list of expenses including: doctors bill $800, Prescriptions $400, New glasses $2000, dental bills $560, braces $5000, Property taxes for their two cars of $800, which included $50 in decal fees, real estate taxes $4500, mortgage interest $12000, Gifts to charities $1,000, GoFunMe contribution to local families in need $100, and Taxes preparation fees for last years taxes $400.

Consider the most beneficial way for Judy and Walter to file their federal income tax return. Prepare a brief written summary that addresses the following:

-Estimated taxable income for Judy and Walter (please show compilations)
-Summary of tax return, including andy suggestions or tax planning consideration
- Explain how you determined the filing status, dependents, and use of standard/ itemized deduction

The specific course learning outcomes associated with this assignment are:

1. Review tax authories and sources of tax law
2. Assess the concepts of gross income and strategies to minimize gross income
3. Examine deductions from income, limitations on those deductions, and strategies for maximizing deductions.

A travel agent wants to estimate the proportion of vacationers who plan to travel outside the United States in the next 12 months. A random sample of 130 vacationers revealed that 40 had plans for foreign travel in that time frame. Construct a 95% confidence interval estimate of the population proportion. Make a statement about this in context of the problem

Two air track gliders of mass 400.0 g and 300.0 g are moving towards each other in opposite directions with speeds of 60.0 cm/s and 100.0 cm/s, respectively. Take the direction of the more massive glider as positive. Use units of "g" and "cm/s" in your calculations.

1. Determine the velocity of each glider after the collision if the collision is elastic. (Use units of "g" and "cm/s" for this question.)
2. The most "inelastic" collision would occur if the two gliders stuck together on impact. If this was the case, find the velocity of the pair after the collision, and the kinetic energy lost as a result of the collision. (Determine the energies in standard units of "J.")

Pam is in charge of putting on the NYE fireworks show. The show can either be anywhere from 10 - 20 minutes long. There are 4 neighborhoods in your city that each offer different views of the firework show, and thus each have a different marginal benefit from additional minutes of the show as shown in the table below:

If each additional minute of the show costs $44, what is the optimal length of the show in minutes?

Since each additional minute of the show costs $44, each of the 4 neighborhoods is required to contribute $11 in taxes for each additional minute. Each neighborhood gets a vote on the maximum number of minutes they want the show to run based on this cost. What is the maximum length of the show that 3 of the 4 neighborhoods would accept?

• Compute the quartiles for each sample period and determine if there are any outliers
