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

86.7

70.1

56.8

90.8

55.7

67.5

76.2

50.8

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.
