Construct and Interpret Confidence Intervals Regarding the Difference of Two Independent Means
-A researcher wishes to determine whether people with high blood pressure can lower their blood pressure by performing yoga exercises. A treatment group and a control group are selected. The sample statistics are given below. Construct a $90 \%$ confidence interval for the difference between the two population means, $\mu _ { 1 } - \mu _ { 2 }$.
Would you recommend using yoga exercises? Explain your reasoning.
Treatment Group Control Group
$$\begin{array} { l l }
\mathrm { n } 1 = 100 & \mathrm { n } _ { 2 } = 100 \
\overline { \mathrm { x } } 1 = 178 & \overline { \mathrm { x } } 2 = 193 \
\mathrm {~s} _ { 1 } = 35 & \mathrm {~s} _ { 2 } = 37
\end{array}$$
