The high temperatures (in degrees Fahrenheit) of a random sample of 7 small towns are:98.896.797.497.696.398.998.2Assume high temperatures are normally distributed. Based on this data, find the 98% confidence interval ofthe mean high temperature of towns. Enter your answer as an open-interval (i.e., parentheses) accurateto two decimal places (because the sample data are reported accurate to one decimal place).98% C.I. =Answer should be obtained without any preliminary rounding. However, the critical value may be roundedto 3 decimal places.
