Question

Construct a 90% confidence interval for μ1−μ2 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 = 1890 calories, s1 = 134 and n1 = 8

Bakery B: x2 = 1712, s2 = 186 calories and n1 = 9

-------------------------------------------------------------------------

The confidence interval construction formula is in the attachment.

Looking for __ <μ1 − μ2< __ (Round to the nearest integer as needed.)
