Using one-factor ANOVA with 30 observations,we find at α = .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?
A)We might now be able to reject the null hypothesis.
B)We surely must reject H0 for 60 observations
C)We cannot reject H0 since we obtained the same F-value.
D)It is impossible to get the same F-value for n = 60 as for n = 30.
