The body temperatures in degrees Fahrenheit of a sample of adults in one small town are: 98.6 97.7 99.5 97 98.2 98.4 96.6 98.5 96.7 99.1 97.1 98.8 Assume body temperatures of adults are normally distributed. Based on this data, find the 90% 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. 90% C.I. =
