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 at least 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 eight mothers and the birth weight of their newborns (in kilograms) are recorded in the accompanying table.
Mother’s Weight Gain .... Newborn’s Birth Weight
18 ............ 4.0
7 ............. 2.5
8 ............. 3.0
22 ............ 4.5
21 ............ 4.0
9 .............. 3.5
8 .............. 3.0
10 ............ 3.5

Construct a scatter plot. Do the results support the findings of the study?
