Test the claim that the samples come from populations with the same mean. Assume that the populations are
normally distributed with the same variance. At the 0.025 significance level, test the claim that the three brands
have the same mean if the following sample results have been obtained. $$\begin{array} { c c c }
\text { Brand A } & \text { Brand B } & \text { Brand } \mathbf { C } \
\hline 32 & 27 & 22 \
34 & 24 & 25 \
37 & 33 & 32 \
33 & 30 & 22 \
