In a random sample of 29 people, the mean commute time to work was 32.8 minutes and the standard deviation was 7.2 minutes. Assume the population is normally distributed and use a t-distribution to construct a 95% c
for the population mean μ. What is the margin of error of µ? Interpret the results.
The confidence interval for the population mean μ is ().
(Round to one decimal place as needed.)
