Using Demonstration 13.2 as a guide, conduct a linear regression analysis for the variables in Exercise 13.1. Write a paragraph summarizing the results of this analysis.

Exercise 13.1

Use the Select Cases command illustrated in Demonstration 13.1 to take a 10% random sample from the larger sample.

Next, use the Scatter/Dot procedure to examine the relationship between alwddly, the independent variable or “X Axis,” and smk_204, the dependent variable or “Y Axis.” What does the scattergram reveal about the nature (linearity, strength, and direction) of the relationship between number of drinks consumed and number of cigarettes smoked per day? Write up your results.
