Question
a random sample of six people, the mean driving distance to work was 25.3 miles and the standard deviation was 7.5 miles. Assuming the population is normally
stributed and using the t-distribution, a 95% confidence interval for the population mean p is (17 4, 33.2) (and the margin of error is 7.9) Through research, it has
een found that the population standard deviation of driving distances to work is 6 2 Using the standard normal distribution with the appropriate calculations for a
andard deviation that is known, find the margin of error and construct a 95% confidence interval for the population mean u Interpret and compare the results.
