Pair of variables would most likely have a negative association:
the amount of time walking home from school and the distance left to arrive home.
Step-by-step explanation:
We need to identify that Which pair of variables would most likely have a negative association:
- the number of baseballs bought and the total cost
Let number of baseballs bought and total cost be denoted by x & y respectively . So , as value of number of baseballs bought(x) increases , total cost (y) increases . Hence , this pair of variables have positive association .
- the temperature and the number of votes a candidate for school president receives
Let the temperature and the number of votes a candidate for school president receives be denoted by x & y respectively . Accordingly , this situation has no relation and so , no association .
- the age of a puppy and its weight
Let the age of a puppy and its weight be denoted by x & y respectively . So , as value of age of a puppy (x) increases , its weight (y) increases . Hence , this pair of variables have positive association .
- the amount of time walking home from school and the distance left to arrive home
Let the amount of time walking home from school and the distance left to arrive home be denoted by x & y respectively . So , as value of amount of time walking home from school (x) increases , the distance left to arrive home (y) decreases . Hence , this pair of variables have negative association .
