Question

Assume that we want to construct a confidence interval. Do one of the following, as appropriate: (a) find the critical value $t_{alpha/2}$, (b) find the critical value $Z_{alpha/2}$, or (c) state that neither the normal distribution nor the t distribution applies. 40 The confidence level is 95%, $sigma$ is not known, and the histogram of 62 player salaries (in thousands of dollars) of football players on a team is as shown. Frequency 30- 20- 10- 0 4000 8000 12000 16000 200m Salary (thousands of dollars) Select the correct choice below and, if necessary, fill in the answer box to complete your choice. - A. $t_{alpha/2}$ = (Round to two decimal places as needed.) - B. $Z_{alpha/2}$ = (Round to two decimal places as needed.) - C. Neither the normal distribution nor the t distribution applies.
