a) HO: = MB and H1: * B b) HO: B and H1: < B = c) HO: = MB and H1: > MB d) HO: and H1: = B Using the data file and run your t-test, what is the P-value when testing whether there is evidence of a difference in the means of scores between teaching Method A (A) and teaching Method B (B)? a) 2.002 b) 5.228 c) 0.0000052284 d) 0.0000026142 Suppose significance level =0.05. What should be your decision on rejecting or not rejecting the null hypothesis on testing whether there is evidence of a difference in the means of scores between teaching Method A (A) and teaching Method B (B)? a) Reject the null hypothesis. b) Fail to reject the null hypothesis. Suppose significance level xx=0.05. What should be your CONCLUSION on rejecting or not rejecting the null hypothesis on testing whether there is evidence of a difference in the means of scores between teaching Method A (A) and teaching Method B (B)? a) There IS evidence of a difference in the means of scores between teaching Method A (A) and teaching Method B (B). b) There is NO evidence of a difference in the means of scores between teaching Method A (A) and teaching Method B (MB).
