QuestionGiven two independent random samples with the following results: $$\begin{array}{ll} n_{1}=16 & n_{2}=8 \\ \bar{x}_{1}=152 & \bar{x}_{2}=125 \\ s_{1}=14 & s_{2}=11 \end{array}$$
Use this data to find the $98 \%$ confidence interval for the true difference between the population means. Assume that the population variances are equal and that the two populations are normally distributed. Copy Data
Step 1 of 3: Find the point estimate that should be used in constructing the confidence interval.
