Assume that we want to construct a confidence interval. Do one of the following, as appropriate: (a) find the critical value f/2. (b) find the critical value Za/2, or (c) state that neither the normal distribution nor the t distribution applies. The confidence level is 95%, o is not known, and the histogram of 55 player salaries (in thousands of dollars) of football players on a team is as shown. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. 1/2 OB. (Round to two decimal places as needed.) Za/2 (Round to two decimal places as needed.)
