Answer:
(a) No association
(b)Negative association
(c)Positive association
Step-by-step explanation:
(a)There is no association between a person's shoe size and length of hair. This is as a result of the fact that one outcome does not affect the other.
(b)The higher the distance traveled, the lower the amount of gas in a car's gas tank. Therefore, there is a negative association between the distance traveled and the amount of gas in a car's gas tank.
(c)The more a student studies, the higher his/her chances of getting a better grade. Thus, there is a positive association between the amount of time studying and the grade in a class.
