Short Answer

Test Hypotheses Regarding the Difference of Two Independent Means
-Test the hypothesis that $\mu _ { 1 } < \mu 2$ . Two samples are randomly selected from normal populations. The sample statistics are given below.
$$\begin{array} { l l } \mathrm { n } _ { 1 } = 15 & \mathrm { n } _ { 2 } = 15 \\\overline { \mathrm { x } } 1 = 25.57 & \overline { \mathrm { x } } 2 = 28.12 \\\mathrm {~s} _ { 1 } = 2.9 & \mathrm {~s} _ { 2 } = 2.8\end{array}$$
