In a random sample of 26 people, the mean commute time to work was 32.6 minutes and the standard deviation was 7.2 minutes. Assume the population is normally distributed and use a t-distribution to construct a 99% confidence interval forthe 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.)The margin of error of u is(Round to one decimal place as needed.)Interpret the results.HD.A. With 99% confidence, it can be said that the population mean commute time is between the bounds of the confidence interval.B. With 99% confidence, it can be said that the commute time is between the bounds of the confidence interval.C. It can be said that 99% of people have a commute time between the bounds of the confidence interval.D. If a large sample of people are taken approximately 99% of them will have commute times between the bounds of the confidence interval.

A standardized test is given to a sixth-grade class. Historically the mean score has been 151 with a standard deviation of 21. The superintendent believes that the standard deviation of performance may have recently decreased. She randomly sampled 23 students and found a mean of 161 with a standard deviation of 18.2898. Is there evidence that the standard deviation has decreased at the α=0.05 level? Step 1 of 5 : State of the hypotheses in terms of the standard deviation. Round the standard deviation to four decimal places when necessary Step 2 of 5 : Determine the critical value(s) of the test statistic. If the test is two-tailed, separate the values with a comma.
