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 za/2, or (c) state that neither the normal 40- distribution nor the t distribution applies. 30- The confidence level is 99%, a 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 8000 120oo 1600 20000 Salary (thousands of dollars) Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. 4/2 (Round to two decimal places as needed.) O B. Z/2 (Round to two decimal places as needed.) OC. Neither the normal distribution nor the t distributien applies.
