Question

What is your conclusion with respect to Factor A? The selections are "Factor A is significant" and "Factor A is not significant."

What is your conclusion with respect to Factor B? The selections are "Factor B is significant" and "Factor B is not significant."

What is your conclusion with respect to the interaction of Factors A and B? The selections are "The interaction is significant" and "The interaction is not significant."

What is your recommendation to the amusement park? Selections are "1. Use method 1; it has a lower sample mean waiting time and is the best method" , "2. Withhold judgement; take a larger sample before making a final decision", "3. Since method is not a significant factor, use either loading and unloading method."

An amusement park studied methods for decreasing the waiting time (minutes) for rides by loading and unloading 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 method 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 method, the type of ride, and interaction. Use = .05. Factor A is method of loading and unloading; Factor B is the type of ride Type of Ride Roller Coaster 47 49 50 52 Long Flume 45 41 49 45 Screaming Demon Method 1 47 47 43 Method 2 a.

b) "Factor A is not significant."

c) "Factor B is not significant."

d)  "The interaction is not significant."

e) "3. Since method is not a significant factor, use either loading and unloading method."
