The high temperatures (in degrees Fahrenheit) of a random sample of 9 small towns are: 96.7 96.5 99.7 97.4 98 98.6 99.2 99.8 98.4 Assume high temperatures are normally distributed. Based on this data, find the 90% 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)
