The idea of insurance is that we all face risks that are unlikely but carry high cost. Think of a fire destroying your home. So we form a group to share the risk: we all pay a small amount, and the insurance policy pays a large amount to those few of us whose homes burn down. An insurance company looks at the records for millions of homeowners and sees that the mean loss from fire in a year is μ = $500 per house and that the standard deviation of the loss is σ = $10,000. (The distribution of losses is extremely right-skewed: most people have $0 loss, but a few have large losses.) The company plans to sell fire insurance for $500 plus enough to cover its costs and profit. (a) Explain clearly why it would be unwise to sell only 100 policies. Then explain why selling many thousands of such policies is a safe business. (b) Suppose the company sells the policies for $600. If the company sells 50,000 policies, what is the approximate probability that the average loss in a year will be greater than $600?

1- Who Corporation (a C-Corporation) and Rose each own 50% of Tardis Corporation’s (a C-Corporation) common stock. On January 1, 2017 Tardis has positive accumulative E&P of $120,000. On December 31, 2017 when its current E&P has deficit of $30,000, Tardis makes a cash distribution of $40,000 each to Who and Rose. Who’s stock basis in Tardis is $35,000. Rose’s stock basis in Tardis is $8,000.

How are Who and Rose each taxed on the distribution?

How would Who and Rose each be taxed if instead they received $50,000 distribution each?

2- Amy owns 500 shares of Dalek Corporation with a stock basis of $50,000. Total outstanding shares of Dalek Corporation are 1,000. Of the remaining 500 shares, 50 shares are owned by River (her daughter), and the remaining 450 shares of Dalek Corporation are owned by an unrelated shareholder. Dalek Corporation has E&P of $640,000.

What are the tax consequences to Amy if in a stock redemption; Dalek redeems 100 shares from Amy for $30,000?

What are the tax consequences to Amy if in a stock redemption; Dalek Corporation redeems 400 shares from Amy for $80,000?

What are the tax consequences to Amy if in a complete termination of her 500 shares; Dalek distributes $140,000 to Amy?

If you were advising Amy between the scenarios listed in part a-c above, which scenario would you advise Amy to proceed with? Amy wishes to pay the least amount of tax and has $150,000 of capital loss from other investments.

3- In a liquidating distribution, Harkness Corporation distributes land to its shareholders. Harkness Corporation acquired the land 3 years ago in a §351 transfer. Harkness Corporation distributes land with FMV of $1,800,000, adjusted basis of $400,000 pro-rata to its two individual shareholders Donna and Rory. Donna and Rory do not get along and are not related to each other. Donna (80%) owner has stock basis of $87,000. Rory (20%) owner has stock basis of $20,000.

What is the tax result to Harkness Corporation on the distribution?

What is the tax result (including basis of the property received) to Donna?

What is the tax result (including basis of the property received) to Rory?

For students who first enrolled in two year public instituitons in a recent semester, the proportion who earned a bachelor's degree within six years was 0.388. The president of a certain college believes that the proportion of students who enroll in her institution have a higher completion rate.

A.) Determine the null & alternative hypotheses.

B.) Explain what it would mean to make a Type I error.

C.) Explain what it would mean to make a Type II error.

A.) State the hypotheses.

H0: _______

H1: _______

(Type integers or decimals. Do not round.).

B.) Which of the following is a Type I error?

1.) The president rejects the hypothesis that the proportion of students who earn a bachelor's degree within six years is 0.388, when, in fact, the proportion is greater than 0.388.

2.) The president rejects the hypothesis that the proportion of students who earn a bachelor's degree within six years is 0.388, when, in fact, the proportion is 0.388.

3.) The president fails to reject the hypothesis that the proportion of students who earn a bachelor's degree within six years is 0.388, when, in fact, the proportion is 0.388

4.) The president fails to reject the hypothesis that the proportion of students who earn a bachelor's degree within six years is 0.388, when, in fact, the proportion is greater than 0.388

C.) Which of the following Type II error

1.) The president rejects the hypothesis that the proportion of students who earn a bachelor's degree within six years is 0.388, when, in fact, the proportion is 0.388.

2.) The president fails to reject the hypothesis that the proportion of students who earn a bachelor's degree within six years is 0.388, when, in fact, the proportion is 0.388.

2b)
A study is done to determine if Company A retains its workers longer than Company B. Company A samples 20 workers, and their average time with the company is five years with a standard deviation of 1.2 years. Company B samples 20 workers, and their average time with the company is 4.5 years with a standard deviation of 0.8. The populations are normally distributed. Is there evidence at the 5% significance level that the true mean retention time is different for A than for B? You may use a confidence interval or a hypothesis test.


2C)
Consider a small scale example, comparing how temperatures have changed in the US from1968 to 2008. The daily high temperature reading on January 1 was collected in 1968 and 2008 for 51 randomly selected locations in the continental US. The locations are the same for both years. Then the difference between the two readings (temperature in 2008 - temperature in 1968) was calculated for each of the 51 different locations. The average of these 51 values was 1.1 degrees with a standard deviation of 4.9 degrees. Does the data provide evidence that the true mean temperature is different in 2008 than in 1968? Justify fully at the 5% significance level.

After rigorous field survey, the insurance company finds that the probability to have cancer is 10% on average. The company offers a fixed rate policy where the premium is $1,000. Reimbursement is $9,000, which is the amount of medical expense you must pay if you get cancer. Suppose there are two types of customers: heavy smoker, who has a probability of 15% of getting cancer. Nonsmoker, who has a probability of 5% of getting cancer.

A) Assuming utility function is ?? = ?? , where x is the amount of money. Calculate utilities for both heavy smoker and nonsmoker. Who will be buying the insurance?

B) What is the expected profit for the insurance company?

Sue T. is a nurse manager for medical-surgical units at a hospital. She is enrolled in a nursing master's degree program at the local university. As part of the requirements for a Nursing Management course, Sue proposes to conduct a study linking nursing interventions with nursing outcomes. She returns to her unit at night for two weeks to audit patient charts and collect the data she needs. She makes copies of the records that are particularly helpful and takes them home to write the final paper. As Sue is developing her paper, she realizes that the information she has collected may be helpful in completing her nursing staff performance evaluations. She decides to collect further patient outcome data for individual nurses to monitor their performance. Has Sue violated ethical principles by collecting data for a college assignment? Why or why not? Has she violated ethical principles by collecting patient data for employee performance evaluations? why or why not? What, if anything, should Sue have done differently in completing her assignment? What, if anything, should Sue have done differently in completing her employee performance evaluations?
