Find the test statistic F to test the hypothesis that the populations have the same mean. Use α = 0.05. $$\begin{array} { l l l }
\hline \text { Brand 1 } & \text { Brand 2 } & \text { Brand 3 } \
\hline \mathrm { n } _ { 1 } = 8 & \mathrm { n } _ { 2 } = 8 & \mathrm { n } _ { 3 } = 8 \
\overline { \mathrm { x } } 1 = 3.0 & \overline { \mathrm { x } } 2 = 2.6 & \overline { \mathrm { x } } 3 = 2.6 \
\mathrm {~s} _ { 1 } = 0.50 & \mathrm {~s} _ { 2 } = 0.60 & \mathrm {~s} 3 = 0.55
