6. Disney World’s Animal Kingdom is a family theme park in Orlando, Florida. One of its longest rides, “Kilimanjaro Safaris,” has a ride time that is normally distributed with a mean of μ = 14 minutes and a standard deviation of σ = 3 minutes. If the ride lasts more than 19 minutes, it is considered too long and the manager must decrease the ride time. (b) What is the z-score that you calculated and then used to find the probability in part a?

7. Students in an experimental psychology class use various techniques to train a rat to move through a maze. At the end of the class, each student’s rat is timed through the maze. Assume the distribution of maze completion times is mound shaped with a mean of 4.74 minutes and a standard deviation of 1.20 minutes. (a) Describe the maze time distribution.
