Question
**Estimating Mean Temperature with Confidence Intervals**

A researcher must estimate the mean temperature (in degrees Fahrenheit) using the following sample temperatures:

- 35.2
- 36.1
- 30.4
- 23.9
- 46
- 46.5
- 45
- 28.7
- 23.5

**Task:**
Assuming the population of temperatures is normally distributed, determine the 98% confidence interval for the mean temperature. 

**Instructions:**
- Round your answers to two decimal places.
- Enter your answer as an interval (LB, UP), where LB is the lower bound and UP is the upper bound.

**Conclusion:**
The researcher is 98% confident that the population average temperature is within the temperature interval [______].
