A medical researcher suspects that the pulse rate of smokers is higher than the pulse rate of non-smokers. Test
the researcherʹs suspicion using α $\alpha$ = 0.05. Assume the two samples are random and independent. $$\begin{array} { l l } \text { Smokers } & \text { Nonsmokers } \\\mathrm { n } _ { 1 } = 100 & \mathrm { n } _ { 2 } = 100 \\\overline { \mathrm { x } } 1 = 87 & \overline { \mathrm { x } } 2 = 84 \\\sigma _ { 1 } = 4.8 & \sigma _ { 2 } = 5.3\end{array}$$
