Question: A recent study offers evidence that the more weight a woman gains during pregnancy, the higher the risk of having a high-birth-weight baby, defined as 8 pounds, 13 ounces, or 4 kilograms (The Wall Street Journal, August 5, 2010). High birth-weight babies are more likely to be obese in adulthood. The weight gain (in kilograms) of seven mothers and the birth weight of their newborns (in kilograms) is recorded below.
Construct a scatterplot. Do the results support the findings of the study?
