Question
### Hypothesis Testing on Student Course Evaluations

A data set includes data from student evaluations of courses. The summary statistics are as follows:

- Sample size (\(n\)) = 83
- Sample mean (\(\bar{x}\)) = 3.65
- Sample standard deviation (\(s\)) = 0.51

Use a 0.10 significance level to test the claim that the population of student course evaluations has a mean equal to 3.75. Assume that a simple random sample has been selected. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim.

#### What are the null and alternative hypotheses?

- **Option A**
  - \(H_0\): \(\mu = 3.75\)
  - \(H_1\): \(\mu > 3.75\)

- **Option B**
  - \(H_0\): \(\mu = 3.75\)
  - \(H_1\): \(\mu < 3.75\)

- **Option C**
  - \(H_0\): \(\mu \neq 3.75\)
  - \(H_1\): \(\mu = 3.75\)

- **Option D (Selected)**
  - \(H_0\): \(\mu = 3.75\)
  - \(H_1\): \(\mu \neq 3.75\)

#### Determine the test statistic.

- Round to two decimal places as needed.
