(a) Using data set SCORES from Problem 5.4, compute a regression equation for predicting the SCIENCE score from the MATH score. Make one plot showing the data points and a regression line and another showing the residuals versus the x-values (use the PLOT statement of PROC REG to do this).

(b) Produce a scatter plot of MATH (x-axis) versus SCIENCE (y-axis). Include the regression line and the 95% Clan the mean of y. Use PROC GPLOT and the appropriate SYMBOL statement to do this.

Problem 5.4

Run the following program to create a SAS data set called SCORES

(3) Generate a correlation matrix of all the test scores plus the overall score. Use the option to omit the simple statistics produced by PROC CORR.

(b) PHYSlCAL is independent of all the other test scores but is correlated to OVERALL. Why?

(c) Write the statements to correlate each of the scores with OVERALL.
