Question: a. Determine the sample correlation coefficients of (1) age with dry weight and (2) age with log10 dry weight. Interpret your results. b. Using Fisher's

a. Determine the sample correlation coefficients of (1) age with dry weight and (2) age with log10 dry weight. Interpret your results.
b. Using Fisher's Z transformation, obtain a 95% confidence interval for p based on each of the correlations obtained in part (a).
c. For each straight-line regression, determine r2 directly by squaring the r obtained in part (a); also determine r2 from the computer output or from the formula r2 = (SSY - SSE)/SSY. Interpret your results.
d. Based on the preceding results, which of the two regression lines provides the better fit? Explain. Does this agree with your earlier conclusion in Problem 1 (d) of Chapter 5?
