Assume that we want to construct a confidence interval. Do one of the following, as appropriate Find the critical value to/2 Find the critical value za/2 State that neither the normal distribution nor the t distribution applies The confidence level is 99%, o is not known, and the histogram of 63 player salaries (in thousands of dollars) of football players on a team is as shown. 4000 12600 O A. ta/2 = 2.66 B. Neither the normal distribution nor the t distribution applies. O C. Za/2 = 2.00 O D. ta/2 = 1.67
