Resveratrol, a compound in grapes and red wine, has been shown to promote weight loss in rodents
Question:
(a) Define the relevant parameter(s) and state the null and alternative hypotheses.
(b) Possible sample results for Species A are shown in Figure 4.6(a) with the mean indicated by a circle on the boxplots. In the sample, is the mean greater for the resveratrol group? Can we necessarily conclude that resveratrol increases the metabolism rate for this species?
Figure 4.6a
(c) Possible sample results for Species B are shown in Figure 4.6(b) and the sample sizes are the same as for Species A. For which of the two species, A or B, is the evidence stronger that resveratrol increases the metabolism rate for this species? Explain your reasoning.
