The high temperatures (in degrees Fahrenheit) of a random sample of 7 small towns are:99.696.597.39897.198.396.8Assume high temperatures are normally distributed. Based on this data, find the 95% confidenceinterval 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 onedecimal place).95% C.I. =Answer should be obtained without any preliminary rounding. However, the critical value may berounded to 3 decimal places.
