Please help me answer these homework questions.

2. An experiment was performed to determine if different exercise programs affect the bone density of rats. All samples were random and independent. Three treatments were compared; see "rat bones.jmp\" for data. Perform an ANOVA, using all 7 steps of hypothesis testing (including checks for normality and equal standard deviation). If you find that any means differ, follow up with Tukey-Kramer HSD and interpret your results. 3. Samples from different brands of margarine were analyzed to determine the level of physiologically active polyunsaturated fatty acids (PAPUFA, measured in percent). See margarinejmp. a. Perform an ANOVA, using all 7 steps of hypothesis testing (including checks for normality and equal standard deviation). If you find that any means differ, follow up with Tukey-Kramer HSD and interpret your results. b. Show calculations for the residual/error associated with the observation in row 1, then explain in a sentence what the resulting number tells you about that tub of margarine.
