1. Tobacco spending is the explanatory variable, and alcohol spending is the response variable. What is the equation of the least-squares regression line?

2.Show a scatterplot of the data. Include the least square regression line on the graph. Describe the form, direction and strength of your data.

3. What % of the variation in alcohol spending is explained by the least squares regression line?

4.Give a 98% confidence interval for the average rate of change of alcohol spending. (Hint: This is another way to say "slope")

5.Are tobacco spending and alcohol spending independent? Perform a test and state the hypotheses, P-value, and conclusion in terms of the question.

6.Make a normal probability plot.Do the points fall around a straight line? (Yes or No) Does the distribution look normal? (Yes or No)
