distance to work was 22.7...

In a random sample of seven people, the mean driving distance to work was 22.7 miles and the standard deviation was 7.7 miles. Assume the population is normally distributed and use the t-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.
