In a random sample of 29 people, the mean commute time to work
was 32.5 minutes and the standard deviation was 7.3 minutes. Assume
the population is normally distributed and use a
t-distribution to construct a 95% confidence interval for the
population mean mu. What is the margin of error of mu? Interpret
the results. Round to one decimal place as needed.

In a random sample of 18 people, the mean commute time to work
was 34.7 minutes and the standard deviation was 7.3 minutes. Assume
the population is normally distributed and use a t-distribution to
construct a 80% confidence interval for the population mean μ. What
is the margin of error of μ? Interpret the results.
