Investors who sell stocks and bonds (except for retirement investment accounts) will need to fill out tax Form 1040. They will also need to complete Schedule D to find the amount of capital gain or loss on sales. If you buy and sell stocks using a broker, the broker should supply the information needed to prepare Schedule D.

Write your name and Social Security number on the first line of the form. If you do not have a Social Security number or want to keep your number private, use 000-22-1111 as the number.

Which one of the following statements is correct about a portfolio that is invested 30% in stock A, 40% in stock B, and 30% in stock C?

A. The expected return of the portfolio is equal to the risk free rate of return plus a risk premium based on a weighted average of the betas of the individual securities and the market risk premium.

B. The expected return on the portfolio is equal to the summation of the returns on the individual securities within the portfolio divided by three.

C. The standard deviation of the portfolio is equal to the summation of the weights of each security multiplied by the standard deviation of each respective security.

Find the regular earnings, overtime earnings, gross earnings, Social Security tax $(6.2 \%)$, Medicare tax $(1.45 \%)$, and state disability insurance deduction $(1 \%)$ for each employee. Assume that no employee will have earned more than the FICA or SDI maximum at the end of the current pay period. Assume that time and a half is paid for any overtime in a 40-hour week.

As the Hispanic population in the United States continues to grow, businesses want to understand what Hispanics like. One study interviewed separate random samples of Hispanic and Anglo customers leaving a bank. Customers were classified as Hispanic if they preferred to be interviewed in Spanish or as Anglo if they preferred English. Each customer rated the importance of several aspects of bank service on a 10-point scale. Here are summary results for the importance of "reliability" (the accuracy of account records, and so on).

$$\begin{array}{|c|c|c|c|} \hline \text { Group } & n & \bar{x} & s_{x} \\ \hline \text { Anglo } & 95 & 6.37 & 0.60 \\ \hline \text { Hispanic } & 86 & 5.91 & 0.93 \\ \hline \end{array}$$

Researchers want to know if there is a difference in the mean reliability ratings of all Anglo and Hispanic bank customers. Check that the conditions for performing significance test are met.

Reliability of a manufacturing network. A team of industrial management university professors investigated the reliability of a manufacturing system that involves multiple production lines (Journal of Systems Sciences & Systems Engineering, March 2013). An example of such a network is a system for producing integrated circuit (IC) cards with two production lines set up in sequence. Items (IC cards) first pass through Line 1 , then are processed by Line 2. The probability distribution of the maximum capacity level $(x)$ of each line is shown below. Assume the lines operate independently. Find the standard deviation of the maximum capacity for each line. Then, give an interval for each line that will contain the maximum capacity with probability of at least .75.

Military radar and missile detection systems are designed to warn a country of an enemy attack. A reliability question is whether a detection system will be able to identify an attack and issue a warning. Assume that a particular detection system has a .90 probability of detecting a missile attack. Use the binomial probability distribution to answer the following questions.

Would you recommend that multiple detection systems be used? Explain.
