Page 190: 15, 35acdg, 41f, 43ab
- For 41f the question asks "Does this plot show evidence of the violation of any assumptions behind the regression? If so, which ones?" Really, what you want to do here is decide: is a linear model appropriate?
- Are there two quantitative variables?
- Does the scatterplot appear roughly linear?
- Does the residual plot show random scatter?
- Does the scatterplot show any blatant outliers?
- For 43ab remember that you are only using the weight (x variable or L1) and % body fat (y variable or L2) and ignoring the waist data.
After you finish your textbook practice, be sure your answers from last night's homework were all correct!
