1) The average commute to work (one way) is 25 minutes according to the 2019 Community Survey. A local union conducts its own study and finds the average commute is 26 minutes. If we assume that commuting times are normally distributed and that the standard deviation is 5 minutes, what is the probability that a randomly selected commuter spends between 25- and 35-minutes commuting one way? ( 1) and 2) Need the distributions shown.) STEP BY STEP
