Question

c. consider the age of the car and the total amount of washer fluid used since the car was purchased. what would one expect to be the relationship between the variables?
a. positive relationship because the total amount of washer fluid used increases as the age of the car increases
b. no relationship because the total amount of washer fluid used is not correlated with the age of the car
c. negative relationship because the total amount of washer fluid used decreases as the age of the car increases
d. positive relationship because the total amount of washer fluid used decreases as the age of the car increases

Explanation:

Step1: Analyze the relationship concept

As the age of the car increases, more time has passed during which washer - fluid is likely to be used. So, the total amount of washer - fluid used is likely to increase.

Step2: Determine the type of relationship

A positive relationship means that as one variable (age of the car) increases, the other variable (total amount of washer - fluid used) also increases.

Answer:

D. Positive relationship because the total amount of washer fluid used increases as the age of the car increases
