Suppose that you analyze data from a randomized block experimental design using 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 completely randomized experimental design and use the one-way ANOVA procedure to reanalyze the data.For the completely randomized design ANOVA,the null hypothesis of equal treatment group means will ______ be rejected.
A)always
B)sometimes
C)never

The outcome of the ANOVA test can vary depending on the design of the experiment. A randomized block design accounts for variability among blocks, potentially leading to different conclusions than a completely randomized design, which does not account for this variability. Therefore, the null hypothesis might still be rejected, or not, depending on how the variability between blocks affected the initial analysis.
