You must estimate the mean temperature (in degrees Fahrenheit) with the following sample temperatures:
36.5
41.7
31.9
56
28.2
40.5
65.7
70.2
46.3
57.6
Find the 99% 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).
99% C.I. =
Answer should be obtained without any preliminary rounding.
