The high temperatures (in degrees Fahrenheit) of a random sample of 10 small towns are:

99.9

98.9

96.6

98

97.9

97.1

96.3

99.3

99.5

97.6

Assume high temperatures are normally distributed. Based on this data, find the 98% confidence interval of the mean high temperature of towns. Enter your answer as anopen-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. However, the critical value may be rounded to 3 decimal places.
