In an experiment to compare the bond strength of two different adhesives, each adhesive was used in five bondings of two surfaces, and the force necessary to separate the surfaces was determined for each bonding. For Adhesive 1, the resulting values were 229, 286, 245, 299, and 259, whereas the Adhesive 2 observations were 213, 179, 163, 247, and 225. Let μ₁ and μ₂ denote the mean bond strengths of Adhesives 1 and 2, respectively. Interpret the 90% distribution-free confidence interval estimate of μ₁ - μ₂ given in the Minitab output shown here:
