The high temperatures (in degrees fahrenheit) of a random sample of 5 small towns are: 99.9 98.4 98.8 98 99.2 assume high temperatures are normally distributed. based on this data, find the 98% 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). 98% c.i. =
