You must estimate the mean temperature (in degrees Fahrenheit) with the following sample temperatures: 33.5 78.5 34.2 30.6 -17,7 65.1 23.7 43.6 14.7 Find the 80% 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). 80% C.I. = Answer should be obtained without any preliminary rounding.
