The high temperatures (in degrees Fahrenheit) of a random sample of 14 small towns are: 97.3 97.2 98.9 99.3 96.3 98.4 98.2

Question

The high temperatures (in degrees Fahrenheit) of a random sample of 14 small towns are:
97.3  97.2
98.9  99.3
96.3   98.4
98.2   99.6
96.4   99.7
98.7   97.7
97.4   97.6
Assume high temperatures are normally distributed. Based on this data, find the 90% 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).
90% C.I. =
Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3
decimal places.
