The body temperatures in degrees Fahrenheit of a sample of adults in one small town are: 98.9 98.1 97.4 99.1 98.3 97.7 97.8 98.5 98.8 Assume body temperatures of adults are normally distributed. Based on this data, find the 9% confidence interval of the mean body temperature of adults in the town. Enter your answer as an open-interval (i.e., parentheses) accurate to 3 decimal places. Assume the data is from a normally distributed population. 99% C.I. =
