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 value Zx/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 histogram of 58 player salaries (in
thousands of dollars) of football players on a team is as shown.
