Given two independent random samples with the following results: n₁ = 15 X₁ = 149 S₁ = 32 1₂ = 15 X2 = 165 $₂ = 33 Use this data to find the 95 % 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. Step 1 of 3: Find the point estimate that should be used in constructing the confidence interval.
