Sample 1 Sample 2 n = 50 n2 = 25 x = 13.6 X2 = 11.6 01 = 2.2 02 = 3 (a) What is the point estimate of the difference between the two population means? (Use x, - x,.) 2 (b) Provide a 90% confidence interval for the difference between the two population means. (Use x, - X,. Round your answers to two decimal places.) 1.04 x to 2.96 (c) Provide a 95% confidence interval for the difference between the two population means. (Use x, - X,. Round your answers to two decimal places.) 0.70 x to 3.30
