In a random sample of 25 people, the mean commute time to work was 30.4 minutes and the standard deviation was 7.3 minutes. Assume the population is normally distributed and use a t-distribution to construct a 99 confidence interval for the population mean muμ. What is the margin of error of muμ? Interpret the results. russellc, September 13, 2018September 14, 2018, Statistics, 0
