Use the data set of Problem 1 in Chapter 5 to answer the following questions.
In Problem 1, Chapter 5

a. Determine the ANOVA tables for the following regressions: (1) dry weight (Y) on age (X) and (2) log10 dry weight (Z) on age (X). The following results will be helpful in reducing computation time:
S2Y|X = 0.23218SSY = 8.16811S2Z|X = 0.0007838SSZ = 4.2276839
b. Use the tables in part (a) to perform the F test for the significance of each straight-line regression. Interpret your results.
