Assume that we want to construct a confidence interval. Do one of the following, as appropriate: (a) find the critical value t2. (b) find the critical value z/2, or (c) state that neither the normal distribution nor the t distribution applies. The confidence level is 90%, o is not known, and the histogram of 54 player salaries (in thousands e dollars) of football players on a team is as shown. 20- 10- Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. tw2= (Round to two decimal places as needed.) O B. Z4/2= (Round to two decimal places as needed.) OC. Neither the normal distribution nor the t distribution applies.
