6. (5 pts) The body temperatures in degrees Fahrenheit of a sample of adults in one small town are: 98.1 98.7 96.3 99.1 | 98.5 99 | 99.8| 96.6 97.4 99.2 98.3 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.
