Assume that we want to construct a confidence interval. Do one of the following, as appropriate: (a) find the critical value ta/ 2. (b) find the critical ON value za/2, or (c) state that neither the normal distribution nor the t distribution applies. 1.6- 1.2- 0.8- 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 0.4- z score is as shown. O- -0.414290 8400 12600-16800 21000 -08 -1.2 -1.6." -2- X Values Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. ta/2= (Round to two decimal places as needed.) OB. Za/2= (Round to two decimal places as needed.) O C. Neither the normal distribution nor the t distribution applies
