Assume that we want to construct a confidence interval. Do one of the 40- following, as appropriate: (a) find the critical value t/2. (b) find the critical 30- value za/2. or (c) state that neither the normal distribution nor the t distribution applies. 20- The confidence level is 95%, o = 3940 thousand dollars, and the histogram of 61 player salaries (in thousands of dollars) of football players on a team is as shown. 10- 0- 4000 8000 1200 1600 2000 Salary (thousands of dollars) Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. /2= (Round to two decimal places as needed.) O B. Za/2 = (Round to two decimal places as needed.) OC. Neither the normal distribution nor the t distribution applies.
