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) state that neither the normal distribution nor the t distribution applies. The confidence level is 99%, o is not known, and the histogram of 56 player salaries (in thousands of dollars) of football players on a team is as shown. (Round to two decimal places as needed.) Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. ta/2= OB. Z/2 Frequency (Round to two decimal places as needed.) O C. Neither the normal distribution nor the t distribution applies. 30- 20- 10- 4000 8000 12000 16000 20000 Salary (thousands of dollars)
