Confidence Interval

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

86.5
73
84.1
77.7
84.9
79.3
87.4
84.4
67.5
86.1
69



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.
