c. matched or paired samples

d. single mean

e. two proportions

f. single proportion

Varsity athletes practice five times a week, on average.

Short answer

This is a single mean test.

Step-by-step solution

Given information

Varsity athletes practise five times a week on average.

Find the suitable hypothesis test for the given information.

Assume that varsity athletes practise for $\mu$hours per week.

The null and alternative hypotheses are stated as follows:

$$\begin{gathered} {\mathrm{H}}_0:\mu =5 \\ {\mathrm{H}}_{\mathrm{a}}:\mu \ne 5 \end{gathered}$$

This demonstrates that this is a single mean hypothesis test.
