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 z/2, or (c) state that neither the normal distribution nor the t distribution applies. The confidence level is 95%, o is not known, and the normal quantile plot of the 17 salaries (in thousands of dollars) of basketball players on a team is as shown. 0.8 0.4 21000 -0.44 0 8 12 42008400 42600 X Values Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. 4/2 (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.
