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: 46.2 47.4 52.4 50.3 42 46.5 50.8 42.9 52.3 52 Use StatKey to get your interval. Find the 99% 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. =
