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 two decimal places (because the sample data are reported accurate to one decimal place). 90% C.I. - Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places. Question Help: M Message instructor O W Rain.
