You must estimate the mean temperature (in degrees Fahrenheit) with the following sample temperatures:

28.9 | 14.3 | 34.2 | 35.2 | 42.7 | 41.3 | 39.7 | 44.2 | 26.8 | 36.2 | 20.4 | 34.6 |

Find the 99% confidence interval. Enter your answer as an **open-interval** (*i.e.*, parentheses) accurate to 3 decimal places. Assume the data is from a normally distributed population.

Step 1

The sample mean (point estimate for the population mean) is calculated as follows:

Step 2

The sample standard deviation is calculated as follows:

Step 3

Sample mean = 33.21.

Sample standard deviation, *s* is 8.735.

The sample size, *n *is 12.

The* t-*critical value for 99% confidence interval...
