Victoria created the scatterplot below based on the data in the table for the ages and heights of some teachers in her school. Teacher Age vs. HeightTeacherAgeHeight (in.)136622287035060444725586862465She wants to see if a teacher’s height depends on his or her age. What did she do wrong when she created the scatterplot?

Question illustration
A
She mixed up the independent and dependent variables.
B
She labeled the x-axis of the scatterplot “Age” when she should have labeled it “Teacher.”
C
She plotted the point (36, 62) when she shouldn’t have.
D
She mixed up the x- and y-coordinates of the point representing teacher 3.
