3. (Problem 2.29 in the textbook) Refer to thmuscle mass problem 1.27 in the textbook. Use data set CH01PR27.txt in Canvas directory code and data - Y (a) Plot the deviations Y - against X; on one graph. Plot the deviations against X; on another graph, using the same scale as the first graph. From your two graphs, does SSE or SSR appear to be the larger component of SSTO? What does it imply about the magnitude of R. (b) Set up the ANOVA table. (c) Test whether or no 1 = 0 using an F test with a = decision rule and conclusion. 0.05. State the alternative, (d) What proportion of the total variation in muscle mass remains "unexplained" when age is introduced in the analysis? Is this proportion relatively small or large ?
