The high temperatures (in degrees Fahrenheit) of a random sample of 9 small towns are:
| 98.2 |
| 97 |
| 98.8 |
| 96.8 |
| 97.8 |
| 99.2 |
| 99.6 |
| 96.6 |
| 97.3 |
Assume high temperatures are normally distributed. Based on this
data, find the 80% confidence interval of the mean high temperature
of towns. Enter your answer as an open-interval
(i.e., parentheses) accurate to two decimal places
(because the sample data are reported accurate to one decimal
place).

Following is the output of descriptive statistics generated by excel:
| Descriptive statistics | |
| X | |
| count | 9 |
| mean | 97.922 |
| sample standard deviation | 1.093 |
| sample variance | 1.194 |
| minimum | 96.6 |
| maximum | 99.6 |
| range | 3 |
The required confidence interval is (97.41, 98.43).
