Construct a 90% confidence interval for H1 - H2 with the sample statistics for mean calorie content of two bakeries' specialty pies and confidence interval construction formula below. Assume the populations are approximately normal with equal variances. Bakery A X1 = 1889 cal Bakery B X2 = 1689 cal S1 = 136 cal S2 = 201 cal n = 6 n2 = 16 1 1 1 + n2 1 + n2 n1 n1 Confidence interval when variances are equal (x1 - x2) –to@ ) - <H4 42< (31 282) +tő, ha (n-1) s + (n2 - 1) sź where @ = and d.f. = n1 + n2 - 2 ny + n2-2 Enter the endpoints of the interval. < P1 -12< (Round to the nearest integer as needed.)
