An article in Technometrics (1999, Vol. 41, pp. 202–211) studied the capability of a gauge by measuring the weights of two sheets of paper. The data follow.

Test the hypothesis that the mean weight of the two sheets is equal (μ1−μ2μ1−μ2)against the alternative that it is not (and assume equal variances). Find the t-stat to 3 decimal places.
