Answer the same questions as in parts (a) and (b) of Problem 1 for each of the regressions of Y on X in Problems 5 through 8 and Problem 10 of Chapter 5. The following results will be helpful:

Required:
a. Determine the AN OVA tables for the following regressions: (1) dry weight (Y) on age (X)and (2) log,0 dry weight (Z) on age (X).The following results will be helpful in reducing computation time:
S2Y\X= 0.23218 SSY = 8.16811 S2Z][X = 0.0007838 SSZ = 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.
