Metabolic rate is defined as oxygen uptake over a fixed period of time, adjusted for body weight.
Theory indicates that, for warm-blooded animals, metabolic rate should increase as ambient temperature falls below body temperature. In Winter 1997 one group of students selected four mice from among those available for study, successively exposed each mouse to three specific temperature conditions, and made five determinations of metabolic rate on each mouse at each temperature. Assume that metabolic rates are normally distributed with the same standard deviation for each mouse at each temperature. If so, what pairwise comparisons and ad hoc linear contrasts among temperature group means would be appropriate. In particular, do the assumptions in Part 1 seem warranted.
