In a random sample of 25 people, the mean commute time to work was 34.4 minutes and the standard deviation was 7 2 minutes. Assume the population is normally distributed and use a t-distribution to construct a 95% confidence interval for the population mean u. What is the margin of error of p? Interpret the results. The confidence interval for the population mean u is (Round to one decimal place as needed.) Help me solve this View an example Get more help - Clear all Check
