Multiple Choice

The following sample data were recently collected in the course of conducting a randomized block analysis of variance.Based on these sample data,what conclusions should be reached about blocking effectiveness and about the means of the three populations involved? Test using a significance level equal to 0.05.

• A)Because F = 0.4195 < critical F = 4.103,we do not reject the null hypothesis and conclude that the three populations may have the same mean value.
• B)Because F = 0.4195 < critical F = 4.103,we reject the null hypothesis and conclude that the three populations do not have the same mean value.
• C)Because F = 0.1515 < critical F = 4.103,we do not reject the null hypothesis and conclude that the three populations may have the same mean value.
• D)Because F = 0.1515 < critical F = 4.103,we reject the null hypothesis and conclude that the three populations do not have the same mean value.
