In a random sample of 22 people, the mean commute time to work was 31.5 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 fo the population mean u. What is the margin of error of u? Interpret the results. The confidence interval for the population mean u is ( 29.4, 33.6) (Round to one decimal place as...
