Use the given degree

**Problem 78: Constructing a Confidence Interval for the Population Mean**

In this problem, you are tasked with using the given degree of confidence and sample data to construct a confidence interval for the population mean, denoted as μ. Assume that the population follows a normal distribution.

**Scenario:**
Thirty randomly selected students took the calculus final exam. The sample mean score was 95, and the standard deviation was 6.6. You need to construct a 99% confidence interval for the mean score of all students.

**Options:**
- A) \(91.68 < \mu < 98.32\)
- B) \(92.95 < \mu < 97.05\)
- C) \(91.69 < \mu < 98.31\)
- D) \(92.03 < \mu < 97.97\)

Your goal is to identify the correct confidence interval based on the given information.
