Question: Problem 10.34 Consider the following two bivariate data sets each consisting of eleven (x, y) pairs. The two data sets have the same x values

Problem 10.34 Consider the following two bivariate data sets each consisting of eleven (x, y) pairs. The two data sets have the same x values but different y values. Dataset I Dataset II xy y 4 4.26 3.10 5 5.68 4.74 6 7.24 6.13 7 4.82 7.26 8 6.95 8.14 9 8.81 8.77 10 8.04 9.14 11 8.33 9.26 12 10.84 9.13 13 7.58 8.74 14 9.96 8.10 of the data sets.

(b) Compute the estimated regression line, coefficient of determination, and sample corre[1]lation coefficient for each of the data sets.

(c) Draw the residual plots for each of the data sets.

(d) Explain why only one of the linear regression models is appropriate even though the regression analysis for data sets I and II lead to the same parameter estimates, the same coefficient of determination, and the same standard errors.
