Test Hypotheses Regarding the Difference of Two Independent Means
-A medical researcher suspects that the pulse rate of drinkers is higher than the pulse rate of non-drinkers. Use the sample statistics below to test the researcher's suspicion. Use $\alpha = 0.05$ .
$$\begin{array} { l l } \text { Drinkers } & \text { Nondrinkers } \\\mathrm { n } _ { 1 } = 100 & \mathrm { n } _ { 2 } = 100 \\\overline { \mathrm { x } 1 } = 86 & \overline { \mathrm { x } } 2 = 83 \\\mathrm {~s} _ { 1 } = 4.8 & \mathrm {~s} _ { 2 } = 5.3\end{array}$$
