You must estimate the mean temperature (in degrees Fahrenheit) with the following sample temperatures:
| 26.6 |
| 58.4 |
| 47.5 |
| 62.2 |
| 33 |
| 49.3 |
| 40.3 |
Find the 98% confidence interval. 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).
98% C.I. =
Answer should be obtained without any preliminary rounding.
First we will calculate the sample mean and sample variance:

The sample mean is :

The 98% confidence interval is calculated as:

Confidence Interval: (29.964,60.696)
