Obtain estimated means for the model with six independent

Fatty Acid. The data in Display 5.21 were obtained from a randomized experiment to estimate the effect of a certain fatty acid (CPFA) on the level of a certain protein in rat livers. Only one level of the CPFA could be investigated in a day’s work, so a control group (no CPFA) was investigated each day as well. (Data from Donald A. Pierce.)

(a) Obtain estimated means for the model with six independent samples, one for each treatment. Determine the residuals and plot them versus the estimated means. Plot the residuals versus the day on which the investigation was conducted. Is there any indication that the methods of this chapter are not appropriate?

(b) Obtain estimated means for the model with 10 independent samples, one from each treatment-day combination. Calculate the ANOVA F -test to see whether these 10 groups have equal means.

(c) Use (a) and (b) and the methods of Section 5.4.1, to test whether the means for the control groups on different days are different. That is, compare the model with 10 different means to the model in which there are 6 different means.
