These data are the weight losses of subjects randomly assigned to one of three 
  diets, and these additional covariates sex, initial age, and body mass index. 
  Is there any evidence from these data that the mean weight loss differs for
  the different diets, after accounting for the effect of the covariates? How big
  are the difference?
