The nutritional quality of shrubs commonly used for feed by rabbits was the focus of a study summarized in the article “Estimation of Browse by Size Classes for Snowshoe Hare” (Journal of Wildlife Management [1980]: 34–40). The energy content (cal/g) of three sizes (4 mm or less, 5–7 mm, and 8–10 mm) of serviceberries was studied. Let μ₁, μ₂, and μ₃ denote the true energy content for the three size classes. Suppose that 95% simultaneous confidence intervals for μ₁ − μ₂, μ₁ − μ₃, and μ₂ − μ₃ are (−10, 290), (150, 450), and (10, 310), respectively. How would you interpret these intervals?
