You may need to use the appropriate appendix table or technology to answer this question.The following results come from two independent random samples taken of two populations.

Sample 1	Sample 2
n1 = 60	n2 = 35
x1 = 13.6	x2 = 11.6
1 = 2.4	2 = 3

(a)What is the point estimate of the difference between the two population 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.) to (c)Provide a 95% confidence interval for the difference between the two population means. (Use

x₁ x₂.

Round your answers to two decimal places.) to
