The high temperatures (in degrees Fahrenheit) of a random sample of 6 small towns are: 99 96.3 97.5 98.9 99.5 97.9 Assume high temperatures are normally distributed. Based on this data, find the 99% confidence interval of the mean high temperature of towns. 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).
