solution

Is there an association between a teacher’s age and how far
he or she lives from school? For each of the following descriptions, draw a
scatterplot of hypothetical data for a sample of 10 teachers that reveal what’s
described. (Be sure to label and put a reasonable scale on both axes.)

a. No association between age and distance

 b. Strong, positive, linear association between age and
distance

c. Moderate, positive, nonlinear association between age and
distance

d. Moderate evidence that older teachers tend to live closer
to school than younger teachers

 e. Very little association between age and distance, except
for a severe outlier
