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 z2, or (c) state that neither the normal distribution nor thet distribution applies. 40- The confidence level is 90%, o = 4009 thousand dollars, and the histogram of 54 player salaries (in thousands of dollars) of football players 30- on a team is as shown. 20- 10- 0- 4000 8000 1200 1600 20000 Salary (thousands of dollars) Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. ta/2= (Round to two decimal places as needed.) OB. Za12= (Round to two decimal places as needed.) OC. Neither the normal distribution nor the t distribution applies. Frequency
