Assume that we want to construct a confidence interval. Do one of the following, as appropriate: (a) find the critical value t12, (b) find the critical value z12, or (c) 40- state that neither the normal distribution nor the t distribution applies. 30- The confidence level 90%, o is not known, and the histogram of 58 player salaries (in thousands of dollars) of football players on a team is as shown. 20어 10- 4000 8000 1200 1600 2000 Salary (thousands of dollars) Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. tu/2= (Round to two decimal places as needed.) O B. Zu/2 = (Round to two decimal places as needed.) OC. Neither the normal distribution nor the t distribution applies.

Question
Assume that we want to construct a confidence interval. Do one of the following, as appropriate: (a) find the critical value t /2; (b) find the critical value z/2, or (c) 40- state that neither the normal distribution nor the t distribution applies. 30- The confidence level is 90%, o is not known, and the histogram of 58 player salaries (in thousands of dollars) of football players on a team is as shown. 20- 10- 4000 Salary (thousands of dollars) 8000 12000 16000 20000 ..... Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. ta/2 = (Round to two decimal places as needed.) В. Za/2 = (Round to two decimal places as needed.) O C. Neither the normal distribution nor the t distribution applies. Frequency
