Question

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

15.5
19.9
39
42
31.8



Find the 95% 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).

95% C.I. = 

Answer should be obtained without any preliminary rounding.
