We changed number of beers to number of beers/weight of person in lb. r =0.9. r2 =0.81. So let\u2019s look at this scatterplot. Overall pattern: in general, the BAC increases with the number of beers you drink. In the first plot, number of beers only explains 49% of the variation in blood alcohol content. But number of beers / weight explains 81% of the variation in blood alcohol content. Additional factors contribute to variations in BAC among individuals (like maybe some genetic ability to process alcohol).", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
