The MTI Enterprise has a total of 300 employees in its two manufacturing location and the headquarters office. Five years ago, a study showed the average commutin distance to work for MTI employees was 6.2 miles with a standard deviation of 3 mile Recently, a follow-up study based on a random sample of 100 employees indicate an average travel distance of 5.9 miles. (i) Assuming that the mean and standard deviation of the original study holk calculate the probability of obtaining a sample mean of 5.9 miles or less? (ii) Based on probability in (i), infer whether the average travel distance may hav changed? (iii) A second random sample of 40 was selected. This sample produced a mea travel distance of 5.9 miles. If the mean for all employees is 6.2 miles and th standard deviation is 3 miles, calculate the probability of observing a sampl mean of 5.9 miles or less?
