Given two independent random samples with the following results: n1=7x‾1=129s1=20 n2=11x‾2=165s2=16 Use this data to find the 99%99% confidence interval for the true difference between the population means. Assume that the population variances are not 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.
