A math professor has two routes he can take to campus. The length of time it takes to drive each
of these routes depends on trafﬁc. Route A has a mean travel time of 20 minutes, with a standard
deviation of 4 minutes. Route B has a mean travel time of 16 minutes, with a standard deviation
of 3 minutes. Assume that both distributions are unimodal and roughly symmetric.
-Today, the z-score for the professor's travel time was −2.1. How many minutes did it take him to drive to campus if he took Route B?
