Answer the following question in typed SAS code.

Question 6: Given the following data: 15 13 12 4 5 14 10 4 6.1 (a) Write a SAS program and compute a correlation matrix; that is, the correlation coefficient between each variable versus every other variable. What is the significance of each? (b) Compute the correlation coefficient between X and Y when the effect of variable Z has been removed. Is It significant? 6.2 From the data for X and Y (a) Compute a regression line (Y on X). Y is the dependent variable, X the independent variable. (b) What is slope and intercept? (c) Are they significantly different from zero? 6.3 Compute three new variables LX, LY and LZ, which are the natural logs of the original values. Compute a correction matrix for the three new variables. Hint: the function to compute a natural log is the LOG function
