Construct a 99% confidence interval for p - p 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 variancos. X1 = 135 mg, 51 = 3.86 mg, ng = 14 *2 = 74 mg, $2 = 2.01 mg, n2 = 15 Stats Confidence Interval when variances are ( * 1 - X 2 ) - be m not equal d.f. is the smaller of n, - 1 or n2 - 1 Enter the andpoints of the interval.
