A Randomized Block Design Experiment Produced the Following Data A)Test to Determine Whether the Treatment Means Differ

A randomized block design experiment produced the following data. $$\begin{array}{l}\text { Treatment }\\\begin{array} { | c | c c c | } \hline \text { Block } & \text { 1 } & \text { 2 } & \text { 3 } \\\hline 1 & 25 & 27 & 25 \\2 & 19 & 18 & 17 \\3 & 15 & 20 & 16 \\4 & 23 & 27 & 20 \\5 & 30 & 31 & 28 \\\hline\end{array}\end{array}$$ A)Test to determine whether the treatment means differ.(Use $\alpha$ = 0.05.)
Test statistic = ____________________ = ____________________
Critical Value = ____________________
Conclusion: ____________________
Interpretation: _______________________________________
B)Test the effectiveness of the blocking variable.(Use $\alpha$ = 0.05.)
Test statistic = ____________________ = ____________________
Critical Value = ____________________
Conclusion: ____________________
Interpretation: ________________________________________
