In a random sample of 11 people, the mean driving distance to work was 25.2 miles and the standard deviation was 7.3 miles. Assume the population is normally distributed and use the t-distribution to find the margin of error and construct a 95% confidence interval for the population mean. Identify margin of error Construct a 95% confidence interval for the population mean (___,___)

In a random sample of 18 people, the mean commute time to work was 31.5 minutes and the standard deviation was 7.2 minutes. Assume the population is normally distributed and use a t-distribution to construct a 95% confidence interval for the population mean muμ. What is the margin of error of muμ? Interpret the results.
In a random sample of five people, the mean driving distance to work was 20.2 miles...
In a random sample of five people, the mean driving distance to work was 20.2 miles and the standard deviation was 5.8 miles. Assuming the population is normally distributed and using the t-distribution, a 95% confidence interval for the population mean μ is (13.0, 27.4) (and the margin of error is 7.2). Through research, it has been found that the population standard deviation of driving distances to work is 6.6.Using the standard normal distribution with the appropriate calculations for a...
