Data from a Randomized Block Design Are Shown in the Following

Data from a randomized block design are shown in the following table. $\begin{array}{c}\quad\quad\quad\text { Treatment Levels }\\\begin{array}{l}\\\text {Block 1}\\\text {Block 2}\\\text {Block3}\end{array}\begin{array}{l}1 \\8 \\6 \\7 \end{array}\begin{array}{l}2 \\5 \\6 \\8 \end{array}\begin{array}{c}3 \\10 \\9 \\8 \end{array}\begin{array}{r}4\\7\\5\\9\end{array}\end{array}$

Using $\alpha$ = 0.05, the appropriate decision for the blocking effects is ________.

A) reject the null hypothesis $\mu$ ₁ $\ge$ $\mu$ ₂ $\ge$ $\mu$ ₃
B) do not reject the null hypothesis $\mu$ ₁ $\neq$ $\mu$ ₂ $\neq$$\mu$ ₃
C) do not reject the null hypothesis $\mu$ ₁= $\mu$ ₂= $\mu$ ₃
D) reject the null hypothesis $\mu$ ₁ $\le$ $\mu$ ₂ $\le$ $\mu$ ₃
E) do nothing
