Question

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.

Set up the ANOVA table (to 1 decimal, if necessary). Round p-value to four decimal places.

The p-value for Factor A is Selectless than .01between .01 and .025between .025 and .05between .05 and .10greater than .10Item 21

What is your conclusion with respect to Factor A?

The p-value for Factor B is Selectless than .01between .01 and .025between .025 and .05between .05 and .10greater than .10Item 23

What is your conclusion with respect to Factor B?

Explanation / Answer

applying two way ANOVA on above:

p-value for Factor A greater than .10

Factor A is not significant

p-value for Factor B is  greater than .10

Factor B is not significant

p-value for the interaction of factors A and B is greater than .10

The interaction of factors A and B is not significant
