Question

d. consider the weight of the car and the horsepower. what would one expect to be the relationship between the variables?
a. no relationship because the horsepower is not correlated as the weight of the car increases
b. negative relationship because the horsepower increases as the weight of the car increases
c. positive relationship because the horsepower decreases as the weight of the car increases
d. negative relationship because the horsepower decreases with the weight of the car

Explanation:

A heavier car generally requires more power to move. So, as the weight of the car increases, one would expect the horsepower to increase as well. A positive relationship means that as one variable (weight) increases, the other variable (horse - power) also increases.

Answer:

C. Positive relationship because the horsepower increases as the weight of the car increases
