Sample 1 Sample 2 n1 = 50 n, = 25 x1 = 13.6 X2 = 11.6 01 = 2.1 02 = 3 (a) What is the point estimate of the difference between the two population means? (Use x, - x2.) (b) Provide a 90% confidence interval for the difference between the two population means. (Use x, - X2. Round your answers to two decimal places.) to (c) Provide a 95% confidence interval for the difference between the two population means. (Use x1 - X2.
