We are interested in finding the mean water temperature of a river during the Spring run off from the nearby mountains. You must estimate the mean temperature (in degrees Fahrenheit) with the following sample temperatures: 53.8 45.2 48.5 50.3 40.8 60.1 45 51.2 49.7 49.7 48.2 Use StatKey _ to get your interval. Find the 9% 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. =
