Chapter 11.4, Problem 11E

An F-test with 12 degrees of freedom in the numerator and 6 degrees of freedom in the denominator produced a test statistic whose value was 3.42. The null and alternate hypotheses were H 0 : σ 1 = σ 2 versus H 0 : σ 1 < σ 2 .

  1. Do you reject H 0 at the α = 0.05 level?
  2. Do you reject H 0 at the α = 0.01 level?

If after performing a t-test for comparison of means (alpha= .05) we obtain p=0.0256, what is our conclusion? a. Fail to reject H0 b. Reject H0 c. Reject H1 d. Unable to determine from the information provided
Dr. Chapman conducted an experiment in which participants watched paint dry for 30 minutes twice, once being paid $1 and once being paid $30. When comparing the samples, he calculated t = 3.57. He assumed α = .01 with df = 5, so the tcv = ±4.032. Because the calculated value was: A. greater than the critical value, Dr. Chapman can reject the null hypothesis. B. greater than the critical value, Dr. Chapman failed to reject the null hypothesis. C. less than the critical value, Dr. Chapman failed to reject the null hypothesis. D. less than the critical value, Dr. Chapman can reject the null hypothesis.
Match the p-values with the appropriate conclusion: I. 0.00001 II. 0.0189 III. 0.0611 IV. 0.4234(a) The evidence against the null hypothesis is significant, but only at the 10% level.   (b) The evidence against the null and in favor of the alternative is very strong.   (c) There is not enough evidence to reject the null hypothesis, even at the 10% level.   (d) The result is significant at a 5% level but not at a 1% level.
