#### Descriptive Statistics

- **Sample Mean**: 6.7333 hours
- **Sample Standard Deviation**: 0.3725 hours

#### Confidence Interval

- **Confidence Coefficient**: 0.98
- **Lower Limit**: Value not specified
- **Upper Limit**: Value not specified

#### Hypothesis Test

- **Hypothesized Value**: 7 hours
- **Test Statistic**: -2.4796
- **P-value (Lower Tail)**: Value not specified
