Question
Assume that we want to construct a confidence interval. Do one of the​ following, as​ appropriate: (a) find the critical value
tα/2​,
​(b) find the critical value
zα/2​,
or​ (c) state that neither the normal distribution nor the t distribution applies.
 
The confidence level is
95​%,
σ
is not​ known, and the histogram of
61
player salaries​ (in thousands of​ dollars) of football players on a team is as shown.

A histogram has a horizontal axis labeled "Salary (thousands of dollars)" from below 0 to above 20000 in increments of 2000 and a vertical axis labeled "Frequency" from 0 to 40 in increments of 10. The histogram contains vertical bars of width 2000, where one vertical bar is centered over each of the horizontal axis tick marks. The heights of the vertical bars are as follows, where the salary is listed first and the height is listed second: 0, 34; 2000, 16; 4000, 1; 6000, 4; 8000, 1; 10000, 4; 12000, 0; 14000, 0; 16000, 0; 18000, 0; 20000, 1.
