A research organization wishes to determine whether four brands of batteries for transistor radios perform equally well. Three batteries of each type were randomly selected and installed in the three test radios. The number of hours of use for each battery is given below. $\begin{array}{lllll}
&&\text { Brand }\
\text { Radio } &1&2&3&4\
A & 25 & 27 & 20 & 28 \
\mathrm{B} & 29 & 38 & 24 & 37 \
\mathrm{C} & 21 & 28 & 16 & 19
\end{array}$ Consider the three different test radios and use Excel to carry out the analysis of variance procedure for a randomized block design. Use a .05 level of significance.
