Assignment:
Interpreting the Coefficient of Determination. In Exercises shown below, use the value of the linear correlation coefficient r to find the coefficient of determination and the percentage of the total variation that can be explained by the linear relationship between the two variables from the Appendix B data sets.
1. r = 0.873 (x = tar in menthol cigarettes, y = nicotine in menthol cigarettes)
2. r =0.744( x = car weight, y = movie gross)
3. r = -0.865 ( x = car weight, y = city fuel consumption in mi /gal)
4. r = -0.488( x =age of home, y = home selling price)
