K 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 40- the critical value za/2, or (c) state that neither the normal distribution nor the t distribution applies. 30- The confidence level is 99%, o= 3811 thousand dollars, and the histogram of 57 player salaries (in thousands of dollars) of football Frequency 20- players on a team is as shown. C 10- O 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. 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
