ID# 0thy 234 9) U.S. internet users spend an average of 13.8 hours a week online. If 68% of users spend between 10.2 and 17.4 hours a week, what is the probability that a randomly selected user is online more than 21.5 hours a week? (hint: use the Empirical rule then use the Z table) M = 1318 The standard deviation is (Answer 4 points) State the Z value (s) (Answer 2 points) State the probability (no statement required) (Answer 4 points) 10) The average commute to work (one way) is 25 minutes according to the 2019 American 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?
