Run the CROSSVALIDATION1 program with 5 replications and a sample size of 1,000.

a. Compare the regression equation results for the original samples of N = 500 and N = 1000. Record the SAMPLE regression weights and R-square values. N = 500 Regression Weight________________ R-square _________ N = 1000 Regression Weight________________ R-square _________

b. Does sample size affect the R-square value? YES ______NO ______.

c. Which sample size would give better estimates of R-square and the regression weight? N = 500 ________ N = 1000 ________
