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 za12, or (c) state that neither the normal distribution nor the t distribution applies. The confidence level is 95%, o= 4130 thousand dollars, and the histogram of 64 player salaries (in thousands of dollars) of football players on a team is as shown.
