Give the best estimate for µ1 ? µ2, the margin of error, the relevant degrees of freedom, and the confidence interval. Assume the results come from random samples from populations that are approximately normally distributed. A 99% confidence interval for µ1 ? µ2 using the sample results ¯x1 = 501, s1 = 115, n1 = 400, and x¯2 = 469, s2 = 96, n2 = 200.
