Using Correct Distribution. In Exercises 5–8, 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.

Miami Heat Salaries Confidence level is 95%, s is not known, and the normal quantile plot of the 17 salaries (thousands of dollars) of Miami Heat basketball players is as shown.
