The lead time of producing a product is measured from the point of raw material acquisition to finished product delivery. Ten randomly selected products of two different specifications are tested and the lead time measured. The data, in days, follow: Spec X: 2.9, 3.4, 2.8, 2.9, 2.7, 3.1, 3.5, 3.2, 3, 2.9 Spec Y: 2.4, 2.2, 3, 2.8, 2.8, 3.3, 2.4, 2.5, 3.2, 2.8 Test the hypothesis that both products have equal mean lead time. Use α = 0.05 and assume both are normally distributed with equal variances.
