Assume that we want to construct a confidence interval. Do one of the following, as appropriate: (a) find the critical value t,a/2. (b) find the critical value za/2, or (c) state that 40 neither the normal distribution nor the t distribution applies. 30- The confidence level is 99%, o is not known, and the histogram of 62 player salaries (in thousands dollars) of football players on a team is as shown. 20- 10- 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. O A. tu/2= (Round to two decimal places as needed.) OB. ZR/2 = (Round to two decimal places as needed.) O C. Neither the normal distribution nor thet distribution applies.
