Test the hypothesis that $\mu _ { 1 }

Question

Test the hypothesis that $\mu _ { 1 } < \mu _ { 2 }$. Two samples are randomly selected from normal populations. The sample statistics are given below.
$$\begin{array} { l l } 
\mathrm { n } _ { 1 } = 15 & \mathrm { n } _ { 2 } = 15 \
\overline { \mathrm { x } } 1 = 24.73 & \overline { \mathrm { x } } 2 = 27.28 \
\mathrm {~s} _ { 1 } = 2.9 & \mathrm {~s} _ { 2 } = 2.8
\end{array}$$
