Test the hypothesis that $\mu _ { 1 } = \mu _ { 2 }$. Two samples are randomly selected from each population. The sample statistics are given below. Use $\alpha = 0.05$.
$$\begin{array} { l c }
\mathrm { n } _ { 1 } = 50 & \mathrm { n } _ { 2 } = 60 \
\overline { \mathrm { x } } 1 = 26 & \overline { \mathrm { x } _ { 2 } } = 24 \
\mathrm {~s} _ { 1 } = 1.5 & \mathrm {~s} _ { 2 } = 1.9
\end{array}$$
