question 42

Multiple Choice

One-way analysis of variance is being used to test the equality of three population means using samples of size 8 from the first population, 11 from the second population and 7 from the third population.The test statistic (F_stat) is 2.712.The significance level is set at 5%.Report your conclusion.

• A)Since the test statistic (F_stat) is greater than the critical value (F_c) for the test, we reject the "no difference" null hypothesis.
• B)Since the test statistic (F_stat) is less than the critical value (F_c) for the test, we cannot reject the "no difference" null hypothesis.
• C)Since the test statistic (F_stat) is greater than the critical value (F_c) for the test, we cannot reject the "no difference" null hypothesis.
• D)Since the test statistic (F_stat) is less than the critical value (F_c) for the test, we reject the "no difference" null hypothesis.
