The body temperatures in degrees Fahrenheit of a sample of adults in one small town are: 98.2 99.1 98.1 98.8 97.1 96.8 97.8 Assume body temperatures of adults are normally distributed. Based on this data, find the 95% 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. 95% C.I. =C Preview

You are given the sample mean and the population standard deviation. Use this information to construct the 90% and 95% confidence intervals for the population mean. Interpret the results and compare the widths of the confidence intervals. From a random sample of 65 dates, the mean record high daily temperature in a certain city has a mean of 84.70°F. Assume the population standard deviation is 14.54°F.
