Question

One-factor ANOVA with two groups is equivalent to a two-tailed t-test.

We might now be able to reject the null hypothesis.

True False

Tukey's test is similar to a two-sample t-test except that it pools the variances for all c samples. True False

Using one-factor ANOVA with 30 observations we find at ? = .05 that we cannot reject the null hypothesis of equal means. We increase the sample size from 30 observations to 60 observations and obtain the same value for the sample F-test statistic. Which is correct? We cannot reject H0 since we obtained the same F-value. It is impossible to get the same F-value for n = 60 as for n = 30. We surely must reject H0 for 60 observations.

We might now be able to reject the null hypothesis.

Explanation / Answer

True

It is impossible to get the same F-value for n = 60 as for n = 30.
