Assume that we want to construct a confidence interval. Do one of the following, as appropriate: (a) find the critical value t Subscript alpha divided by 2 t/2, (b) find the critical value z Subscript alpha divided by 2 z/2, or (c) state that neither the normal distribution nor the t distribution applies. The confidence level is 90%, =3835 thousand dollars, and the histogram of 57 player salaries (in thousands of dollars) of football players on a team is as shown.

Select the correct choice belowand, ifnecessary, fill in the answer

A. t/2= (Round to two decimal places asneeded.)

B. z/2=(Round to two decimal places asneeded.)

C. Neither the normal distribution nor the t distribution applies.
