In a random sample of six ​people, the mean driving distance to work was 23.1 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 95​% confidence interval for the population mean mu. Interpret the results.

The margin of error is approximately 7.02 miles, and the 95% confidence interval for the population mean driving distance to work is (16.08 miles, 30.12 miles). This means we are 95% confident that the true population mean driving distance to work falls within this range.
