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 2t/2,

(b) find the critical value

z Subscript alpha divided by 2z/2,

or (c) state that neither the normal distribution nor the t distribution applies.The confidence level is

90%, sigmaequals=4016 thousand dollars, and the histogram of 65 player salaries (in thousands of dollars) of football players on a team is as shown.
