The U.S. Department of Transportation reported recently that all commuters in the NewYork City area average 120 minutes on the road travelling to and from work eachworkday. Assume that the standard deviation for the amount of time all commuters inthe New York City area travel to and from work each workday equals 30 minutes.a) If a random sample of 36 commuters in the New York City area is selected, calculatethe associated standard error of the mean..b) What is the probability that mean travel time for the commuters in the sample isbetween 113.5 and 122.5 minutes?

Let X be the travel time of the commuters with .
