You are managing a risky portfolio with an expected rate of return of 17% and a standard deviation of 27%. You think that this risky portfolio is best one that you can construct to deliver the best tradeoff between risk premium and return. The T-bill rate is 7%.

Suppose your risky portfolio includes the following investments in the given proportions:

Stock A … 27%

Stock B … 33%

Stock C … 40%

1.) Eric just had a baby last year and he needs money. So he decides to invest in your risky portfolio a proportion (y) of his total investment budget so that his overall portfolio will have an expected rate of return of 15%.

(a) What is the proportion y? (2pts)

(b)What are your client’s investment proportions in your three stocks and the T-bill fund? (4pts)

(c) What is the standard deviation of the rate of return on your client’s portfolio? (2pts)

2.) Now Eric’s wife is a little bit worried about the risk of the new portfolio. She wanted Eric to make sure that the overall portfolio’s standard deviation should not exceed 20%.

(a) What is the investment proportion, y? (2pts)

(b) What is the expected rate of return on the overall portfolio? (2pts)

1. Heart rates are determined before and 30 minutes after a Kettleball workout. It can be assumed that heart rates (bpm) are normally distributed. Use the data provided below to test to determine if average heart rates prior to the workout are significantly lower than 30 minutes after a Kettleball workout at the 0.10 level of significance. Let μ1μ1 = mean before workout.

Select the correct Hypotheses:

Conclusion:

• Fail to Reject H0H0
• Reject H0H0

Interpret the conclusion in context:

• There is not enough evidence to suggest the mean bpm before a Kettleball workout is lower than 30 minutes after the workout.
• There is enough evidence to suggest the mean bpm before a Kettleball workout is lower than 30 minutes after the workout.

In what ways do advertisers in magazines use sexual imagery to appeal to youth? One study classified each of 1509 full-page or larger ads as "not sexual" or "sexual," according to the amount and style of the dress of the male or female model in the ad. The ads were also classified according to the target readership of the magazine. Here is the two-way table of counts.

(a) Summarize the data numerically and graphically. (Compute the conditional distribution of model dress for each audience. Round your answers to three decimal places.)

(b) Perform the significance test that compares the model dress for the three categories of magazine readership. Summarize the results of your test and give your conclusion. (Use α = 0.01.Round your value for χ² to two decimal places, and round your P-value to four decimal places.)

Conclusion

Fail to reject the null hypothesis. There is not significant evidence of an association between target audience and model dress.Reject the null hypothesis. There is significant evidence of an association between target audience and model dress.    Fail to reject the null hypothesis. There is significant evidence of an association between target audience and model dress.Reject the null hypothesis. There is not significant evidence of an association between target audience and model dress.

(c) All of the ads were taken from the March, July, and November issues of six magazines in one year. Discuss this fact from the viewpoint of the validity of the significance test and the interpretation of the results.

The Chahad Bank wants to open a new branch in a distant city with very different economic conditions. Currently, the bank has an expected return of 15% with a standard deviation of 7%. The new branch is expected to have a return of 20% with a standard deviation of 10%. The correlation between the bank's returns and the returns from the new branch is -0.3. The new branch is expected to contribute 10% of the bank's revenues. What is the expected return for the bank if they add the new branch?
