Commute Time to Work The average commute to work (one way) is 25 minutes according to the 2005 American Community Survey. If we assume that commuting times are normally distributed and that the standard deviation is 6.1 minutes, calculate the probability that a randomly selected commuter spends for the following cases. Round the final answers to at least four decimal places and intermediate z-value calculations to two decimal places. Part 1 of 2 (a) More than 41 minutes commuting one way P(X>41)-0.0044 Part: 1/2 Part 2 of 2 (b) Less than 21 minutes commuting one way P(X<21)-
