Normal Distribution Problem
I am not sure how to go about this problem without an xvalue.
1) The mean commute time to work for residents of New York Cityis 34.8 minutes with a standard deviation of 8.84 minutes. The meancommute time to work for residents of San Diego is 23.5 minuteswith a standard deviation of 6.54 minutes. A randomly selected NewYorker took 25.5 minutes while a randomly selected San Diegan took17.1 minutes to commute to work.
a) How much shorter was the San Diegan’s commute time?
b) Assume each distribution in that problem isapproximately normal. Relative to the city, who had the shortercommute?
