Use the sample data below to test the hypotheses

:

: Not all population proportions are the same

Populations
Response 1 2 3
Yes 200 200 91
No 150 200 109

where is the population proportion of yes responses for population . Using a level of significance 0.05.

The p-value is - Select your answer -less than .005between .005 and .01between .01 and .025between .025 and .05between .05 and .10greater than .10

What is your conclusion?
- Select your answer -Conclude not all population proportions are equal.Conclude all population proportions are equal.

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,...
