Two-tailed main effects hypothesis

WebThis research question requires three hypotheses, two main effect and one interaction effect: H01: There is no difference in students’ attitudes toward math as measured by the Attitudes Toward Mathematics Inventory based on type of math program the second grade student participated in. (This hypothesis attends to the first main effect.) WebIt is the opposite of your research hypothesis. The alternative hypothesis--that is, the research hypothesis--is the idea, phenomenon, observation that you want to prove. If you suspect that girls take longer to get ready for school than boys, then: Alternative: girls time > boys time. Null: girls time <= boys time.

But, if it's a two-tailed hypothesis test and z=1.95, we must multiply the p-value of 0.0256 by two. Hence, the correct p-value is 0.0512 for the two-tailed hypothesis test.
