Suppose that you analyze data from a completely randomized experimental design using a one-way ANOVA.At the 5% level of significance,you reject the null hypothesis of equal treatment group means.You find out later that the data was actually from a randomized block experimental design and use the ANOVA procedure to reanalyze the data.For the randomized block design ANOVA,the null hypothesis of equal treatment group means will ______ be rejected at the 5% level of significance.
A)always
B)sometimes
C)never

Using a randomized block design ANOVA can account for variability due to blocks, potentially leading to a more precise estimate of treatment effects compared to a completely randomized design. This can either increase or decrease the likelihood of rejecting the null hypothesis, depending on how much of the variability is explained by the blocks.
