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:

In general, a heavier car requires more power to move. So, as the weight of the car increases, more horsepower is needed. This implies a positive relationship where an increase in one variable (weight) leads to an increase in the other (horse - power).

Answer:

None of the given options are correct. A positive relationship exists because horsepower increases as the weight of the car increases.
