Test the indicated claim about the means of two populations. Assume that the two samples are independent and that they have been randomly selected.
-A researcher wishes to determine whether people with high blood pressure can reduce their blood pressure by following a particular diet. Use the sample data below to test the claim that the treatment population mean µ1 is smaller than the control population mean µ2. Test the claim using a significance level of 0.01.
$\begin{array} { l }
\text { Treatment Group }& \text { Control Group}\\hline
\mathrm{n}_{1}=85 &\mathrm{n}_{2}=75 \
\overline{\mathrm{x}_{1}}=189.1 & \overline{\mathrm{x}_{2}}=203.7 \
\mathrm{~s}_{1}=38.7 & \mathrm{~s}_{2}=39.2
\end{array}$
