Given two independent random samples with the following results: n1=15x‾1=125s1=26 n 1 =15 x ‾ 1 =125 s 1 =26    n2=11x‾2=159s2=23 n 2 =11 x ‾ 2 =159 s 2 =23 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.

Step 2 of 3 : Find the standard error of the sampling distribution to be used in constructing the confidence interval. Round your answer to the nearest whole number.

Step 3 of 3: Find the lower and upper limits of the confidence interval
