Construct a 95% confidence interval for Hy - 2 with the sample statistics for mean cholesterol content of a hamburger from two fast food chains and confidence interval construction formula below Assume the populations are approximately normal with unequal variances. Stats x, = 121 mg, s, = 3.88 mg, n, = 15 *2 = 93 mg, $2 = 2 22 mg, n2 = 19 Confidence interval when variances are not equal ( * 1 - X 2 ) - 10 / my + me = 149 - 12= ( X1 - X 2 ) + le d.f. is the smaller of n, - 1 or n2 - 1 Enter the endpoints of the interval OH, - 12
