From the data for X and Y in Problem 5.1:

(a) Compute a regression line (Yon X). Y is the dependent variable, X the independent variable.

(b) What is slope and intercept?

(c) Are they significantly different from zero?

Problem 5.1

Given the following data:

(a) Write a SAS program and compute the Pearson correlation coefficient between X and Y;X and Z. What is the significance of each?

(b) Change the correlation request to produce a correlation matrix; that is, the correlation coefficient between each variable versus every other variable.
