Ethan wants to know how long (in minutes) it takes to walk from the State Library tothe Peter Hall Building. Over the past ten days, Ethan records the time (in minutes)needed for him to finish the trip, as follows:16.8 12.5 17.2 14.1 14.5 13.2 15.6 14.6 14.8 13.6Assuming a normal distribution N(ux,o3) for these observations, please answer thefollowing:(a) If o? is unknown, calculate a 95% confidence interval for the mean µx.(b) Find a 90% confidence interval for o.(c) Assume ox = 2 minutes and that you want a 95% confidence interval of width 2(i.e. ±1). How many experiments are needed?
