In a random sample of twelve people, the mean driving distance to work was 20.8 miles and the standard deviation was 5.4 miles. Assume the population is normally distributed and use thet-distribution to find the margin of error and construct a 99% confidence interval for the population mean mu. Interpret the results. Identify the margin of error.

what is the margin of error and the confidence interval?
Question Help In a random sample of seven people, the mean driving distance to work was 24.7 miles and the standard deviation was 6.6 miles. Assuming the population is normally distributed and using the I-distribution, a 90% confidence interval for the population mean is (15.5, 33.9) (and the margin of error is 9.2). Through research, it has been found that the population standard deviation of driving distances to work is...
