The following results come from two independent random samples taken of two populations. Sample 1 : n1 = 60; x1 = 13.6 ; Ï1 = 2.4.
Sample 2 : n2 = 35 ; x2 = 11.6; Ï2 = 3.
(a) What is the point estimate of the difference between the two populations means? (Use x1 ? x2.)
(b) Provide a 90% confidence interval for the difference between the two population means. (Use x1 ? x2. Round your answers to two decimal places.)
(c) Provide a 95% confidence interval for the difference between the two population means. (Use x1 ? x2. Round your answers to two decimal places.)
