A researcher must estimate the mean temperature (in degrees Fahrenheit) with the following sample temperatures: 78.1 70.7 73.8 80.1 63.1 66.8 69 78.1 66.4 76.5 70.7 68.5 Assuming the population of temperatures are normally distributed, find the 95% confidence interval. Round the answers to two decimal places. Enter your answer as an interval of the form (LB, UP). The researcher is 95% confident that the population average temperature is within the temperature interval
