Question
Assume that we want to construct a confidence interval. Do one of the following, as appropriate: (a) find the critical value \( t_{\alpha/2} \), (b) find the critical value \( z_{\alpha/2} \), or (c) state that neither the normal distribution nor the t distribution applies. The confidence level is 99%, \( \sigma = 4107 \) thousand dollars, and the histogram of 60 player salaries (in thousands of dollars) of football players on a team is as shown. **Histogram Description:** - The horizontal axis represents Salary (in thousands of dollars) ranging from 0 to 20,000. - The vertical axis represents Frequency. - The histogram shows: - A peak around the lower salary range (0–4,000), with frequency nearly at 40. - A sudden drop beyond 4,000 with sparse occurrences up to 20,000. **Options:** - **A.** \( t_{\alpha/2} = \_\_ \) - (Round to two decimal places as needed.) - **B.** \( z_{\alpha/2} = \_\_ \) - (Round to two decimal places as needed.) - **C.** Neither the normal distribution nor the t distribution applies.
