6. What discount rate results in the maximum NPV for this project? What is that maximum NPV? Write a note to your client (or an old-school boss), who has little knowledge about the “Solver”, explaining what parameters you chose as inputs in the solver and what you asked the solver to do. Be sure to refer to the cell ID (e.g. cell D52) where appropriate so your client/boss can follow what you are talking about.

Thirteen students entered the undergraduate business program at Rollins College 2 years ago. The following table indicates what their grade point average (GPAs) were after being in the program for 2 years and what each student scored on the SAT exam (maximum 2400) when he or she was in high school.

a. Is there a meaningful relationship between grades and SAT scores?

b. If a student scores a 1200 on the SAT, what do you think his or her GPA will be?

c. What about students that score 2400?

EXERCISE 13.4

An 18-year-old student donated for the first time at a blood drive at his high school.

1. Concerned that he may have contracted HIV before the donation, what instructions should he follow to prevent his unit from being transfused?
2. Why are questions regarding HIV important even when tests are performed to detect the virus?

EXERCISE 14.5

Previous testing on a donor’s computer record indicates CMV antibody–negative. The most recent donation demonstrates that antibodies are currently present.

1. Can the donor still donate?

2. Why has the CMV antibody test result changed?

3. What patients require the transfusion of CMV-reduced-risk blood products?

4. What alternatives exist in the provision of CMV antibody–negative blood?

Barb and Barney are married and file a joint return. They have two children, Lulu and Zoe, that live at home and whom they fully support. Lulu is 9 and Zoe is 13 years old. In order for Barb and Barney to both work, they pay care providers to take care of Lulu and Zoe after school. The total care cost for the year were: Lulu $4,800, and Zoe $3,800. During the year Barb earned salary of $24,500 and Barney earned salary of $25,000 and they each made a deductible $5,000 contribution to a traditional spousal IRA. Neither Barb nor Barney are covered by qualified plans at work. Calculate the dollar amount of Barb and Barney’s tax credit for child and dependent care expenses. Show your work including all calculations.

Hand volume can be determined by measuring the amount of water displaced in a beaker after the hand is dipped in it. A student read a report that the median hand-volume of college-age males is 400ml. To test whether this is true at her school, she convinced 12 of her male friends to dip their hands in a beaker of water. Her measurements (in ml) are below:

400 360 420 520 460   350 500 420 450 430 395 400

1. Report the null and alternate hypotheses for a sign test
2. Report the number of positive and negative signs (remember this is based on a hypothesized median volume of 400 ml)
3. Report the P value and test statistic, do you accept or reject the null hypothesis?
4. Use a signed-rank test to re-run the analysis above.

A person bets his remaining savings on a horse race based on the large payoff if his horse wins. Which of the following decision-making criteria does this typify?

Choose one answer.

Jake woke up late in the morning on the day that he has to go to school to take an important test. He can either take the shuttle bus which is usually running late 20% of the time or ride his unreliable motorcycle which breaks down 40% of the time. He decides to toss a fair coin to make his choice. If Jake, in fact, gets to the test on time, what is the probability that he took the bus?

Choose one answer.

Explore alternative schooling options for Children. Did you know that Home Schooling is on the rise? Did you know that private schools are available, but how much do they really cost? Were you aware that there are online schools that children can attend like a charter school (they are public schools)? Are the social aspects really a concern in today's world of teams, clubs, recreational activities, and other groups in which kids are involved? Look at at least two different types of education for children and comment on what you find. A brief summary of each is fine, or you can compare and contrast the two. You could even compare and contrast each with typical public schools. Have fun with it! Be sure to include all websites that you visit and utilize in your assignment (a minimum of two are required).

Suppose you have a STAT class from 8:30–9:30 and an ECON class from 9:30–10:30. Assuming you arrive to school at 8:30 with zero text messages on your cell phone and you receive 6 texts every 45 minutes on average, find the following probabilities.

a)Based on the information above, find the probability that you receive at least 3 texts during your STAT class. N.B. I suggest you find these in R studio.

b)find the probability that you receive exactly 3 texts during your STAT and exactly 3 texts during ECON. I suggest you find these in R.

c)find the probability that you receive your 10th text during ECON.
