Assume that we want to construct a confidence interval. Do one of the following, as appropriate: (a) find the critical value to/2, (b) find the critical value Zα/2, or (c) state that neither the normal distribution nor the t distribution applies. The confidence level is 90%, o is not known, and the histogram of 63 player salaries (in thousands of dollars) of football players on a team is as shown. OA. ta/2= B. (Round to two decimal places as needed.) Frequency Za/2 = (Round to two decimal places as needed.) O C. Neither the normal distribution nor the t distribution applies. 40- 30- 20- Select the correct choice below and, if necessary, fill in the answer box to complete your choice. 10- 0 4000 8000 12000 16000 20000 Salary (thousands of dollars)

Assume that we want to construct a confidence interval. Do one of the following, as appropriate: (a) find the critical value to/2, (b) find the critical value Zx/2, or (c) state that neither the normal distribution nor the t distribution applies. The confidence level is 90%, o is not known, and the histogram of 63 player salaries (in thousands of dollars) of football players on a team is as shown. A. B. ta/2= (Round to two decimal places as needed.) Frequency Zα/2 (Round to two decimal places as needed.) C.
