Use the following information for the next four problems. Researchers believe that body temperatures for a particular population vary according to a normal model. They want to estimate , the mean body temperature for that population. They randomly select a group of 17 adults and record the body temperature for each person. That data results in a sample mean of 98.3 F and a sample standard deviation of 0.68 F. Calculate a 90% confidence interval for estimating the mean. a. 98.3 0.29...
