Question
According to a magazine, people read an average of more than three books in a month. A survey of 25 random individuals found that the mean number of books they read was 2.8 with a standard deviation of 1.23.

### Questions to be Addressed:
a. To test the magazine's claim, what should the appropriate hypotheses be?
b. Compute the test statistic.
c. Using a level of significance of 0.05, what is the critical value?
d. Find the p-value for the test.
e. What is your conclusion?

#### Detailed Explanation:
a. **To test the magazine's claim, what should the appropriate hypotheses be?**

To determine the null hypothesis \( H_0 \) and the alternative hypothesis \( H_1 \):

\[ H_0: \mu = 3 \]
\[ H_1: \mu > 3 \]

(Type whole numbers.)
