Question

a-26. the graph below compares the age and the number of pets for a certain population. describe the association for this population.

Explanation:

Examine the scatter - plot. As age increases from around 25 to 40, the number of pets generally seems to increase from lower values (around 1 - 2) to higher values (up to 10). After 40, the number of pets seems to decrease. So, there is a non - linear relationship. First, there is a positive association as age increases from 25 to 40, and then a negative association as age increases past 40.

Answer:

There is a non - linear association. Initially, as age increases from approximately 25 to 40 years, there is a positive association between age and the number of pets. After 40 years of age, there is a negative association between age and the number of pets.
