The following information is obtained from two independent samples selected from two populations. nį = 117,x1 = 23.4, ở1 = 5.6 n2 = 168,32 26.0, o2 = 5.7 a. What is the point estimate of 41 – 42? The point estimate for µ41 – 42 is -2.6 b. Determine the 95% confidence interval for u1 – H2, and find the margin of error for this estimate. Round your answers to two decimal places. The 95% confidence interval for 41 H2 is from i to i ,with the margin of error i|
