In a random sample of ten people, the mean driving distance to work was 23.2 miles and the standard deviation was 7.4 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 u. Interpret the results. Identify the margin of error. 5.3 miles (Round to one decimal place as needed.) Construct a 95% confidence interval for the population mean. (Round to one decimal place as needed.)
