3. A medical research team wants to investigate how a new type of steroid medication affects levels of cortisol in the bloodstream. 25 patients with rheumatoid arthritis are recruited to conduct a study, and assigned randomly to one of two groups. One group of 12 subjects are given an older standard drug while another group of 13 patients are given the new medication. After a month the cortisol levels of patients in both groups are measured by a blood assay. A summary of the data for both groups is below. Old drug $\bar{y}_1 = 180$ $s_1 = 64$ $n_1 = 12$ New drug $\bar{y}_2 = 234$ $s_2 = 82$ $n_2 = 13$ (a) Are these paired or independent samples? Explain your answer. (b) Does the new drug have an effect on the cortisol level? Conduct an appropriate hypothesis test using a significance level $\alpha = 0.05$. Perform the test using i) a critical value and ii) the p-value. Clearly state your conclusion. (c) What type of error could you have made in taking your decision in (b)? Give a definition of the probability of making such error. (d) If a significance level of $\alpha = 0.01$ were considered for the test in (b), would your conclusion have been different? Discuss.

You have just started your summer internship, and your boss asks you to review a recent analysis that was done to compare three alternative proposals to enhance the firm's manufacturing facility. You find that the prior analysis ranked the proposals according to their IRR, and recommended the highest IRR option, Proposal A. You are concerned and decide to redo the analysis using NPV to determine whether this recommendation was appropriate. But while you are confident the IRRs were computed correctly, it seems that some of the underlying data regarding the cash flows that were estimated for each proposal was not included in the report. For Proposal B, you cannot find information regarding the total initial investment that was required in Year 0. And for Proposal C, you cannot find the data regarding additional salvage value that will be recovered in Year 3. Here is the information you have (in $ millions): Suppose the appropriate cost of capital for each alternative is 10%. Using this information, determine the NPV of each proposal. Which project should the firm choose? Why is ranking the projects by their IRR not valid in this situation? Fill in the missing values ($ millions). (Round to two decimal places.) Proposal IRR Year 0 Year 1 Year 2 Year 3 A 60.00% -$100 $30 $153 $88 B 56.69% $ $0 $206 $95 C 57.98% -$100 $37 $0 $
