An amusement park studied methods for decreasing the waiting time (minutes) for rides by loading and uploading riders more efficiently. Two alternative loading/unloading methods have been proposed. To account for potential differences due to the type of ride and the possible interaction between the methods of loading and unloading and the type of ride, a factorial experiment was designed. Use the following data to test for any significant effect due to the loading and unloading methods, the type of ride, and interaction. Use α = .05. Use both p-Value and Critical-Value approaches.
