Im not sure if I got the right answer

14. What does it mean for data (ANY data, not just the data above) to be statistically signicant? a. It means that the data is very important b. It means that the data gives you NO reason to question the null hypothesis c. d. It means that the probability you calculate is very high It means that the data gives you reason, within some level of tolerance, to reject the null hypothesis in favor of the alternate hypothesis e. It means nothing. Survey class 1 averaged 81.79 While survey class 2 averaged 75.8] on a test. We see that class 1 had a higher average grade than class 2. The data is posted to uLearn. Use this data for questions 15-20. Does the data support the assertion that class 1 did significantly better than class 2 at LOC a = .01 ? and z = , and the table used is determined by the smaller 11. The test statistic is: [m = 2 2 s. S: (Ln "1 "2 1"'1 "2 15. State the null hypothesis: a. Ho: M /2 16. State the alternate hypothesis: a. H: 4/217. Determine the rejection region(s); what are they? Sketch them on the curve below: a. 2.0518 b. 1.7011 c. 2.4733 d. 1.7033 e. 1.6450 18. Calculate the test statistic using the equation on the previous page: a. 3.85 b. 2.43 c. 1.28 d. 1.69 e. 2.28 19. Plot the test statistic on the curve and state your conclusion: . The test statistic is not in the rejection region so we fail to reject Ho- b. The test statistic is in the rejection region so we reject H. c. The data is statistically insignificant. d. Both b. and c. e. Both a. and c
