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

24.7

30.9

23.9

36.6

19

30.1

20.6

27.3

26.4

22.7

Find the 90% 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). For example, if your lower bound is 64 and your upper bound is 72, you would enter that as (64,72). 90% C.I. =
