Babies born with low birth weights (less than 2500 grams) are at an increased risk for many infant diseases. Researchers in North Carolina collected data to see what variables may influence the birth weight (in grams) of a child, including whether the mother drank alcohol during pregnancy, whether the mother smoked during pregnancy, the mother's age (years), the gestation of the pregnancy (number of weeks from conception until birth), the mother's race, the length of the birth (hours), and several others. The plot below summarizes some of the variables measured.
-What type of plot would be appropriate for examining the relationship between a mother's age and her baby's birth weight?
A) Scatterplot
B) Side-by-side boxplots
C) Segmented bar graph
D) Dotplot
