Question
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.

The confidence level is 95%, \(\sigma\) is not known, and the histogram of 58 player salaries (in thousands of dollars) of football players on a team is as shown.

**Histogram Description:**
- The x-axis represents the salary in thousands of dollars, ranging from 0 to 20,000.
- The y-axis indicates the frequency of players.
- Most player salaries are concentrated in the range of 0 to 4000 thousand dollars, with frequency peaking around 35.
- Frequencies drop significantly beyond this range.

Select the correct choice below and, if necessary, fill in the answer box to complete your choice.

\( \circ \) A. \( t_{\alpha/2} = \) [ ]
(Round to two decimal places as needed.)

\( \circ \) B. \( z_{\alpha/2} = \) [ ]
(Round to two decimal places as needed.)

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