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 za /2, or (c) state that neither the normal distribution nor the t distribution applies. 40- 30- The confidence level is 99%, o = 3701 thousand dollars, and the histogram of 63 player salaries (in thousands of dollars) of football players on a team is as shown. Frequency 20- 10- 0 - 0 4000 8000 12000 16000 20000 Salary (thousands of dollars) . . . Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. ta/2= (Round to two decimal places as needed.) O B. Za/2= (Round to two decimal places as needed.) O C. Neither the normal distribution nor the t distribution applies
