What can you say about the correlation between the age of a car and its resale value?
a. the trend line slopes downward from upper left to lower right, so there is a negative correlation between a car’s age and its resale value.
b. the trend line slopes downward from upper left to lower right, so there is a positive correlation between a car’s age and its resale value.
c. the trend line slopes upward from lower right to upper left, so there is a positive correlation between a car’s age and its resale value.
d. there is no correlation between a car’s age and its resale value.

Option A) The trend line slopes downward from upper left to lower right, so there is a negative correlation between a car’s age and its resale value.  

Step-by-step explanation:

We have to find about the correlation between the cars age and the resale value.

Correlation is a technique that help us to find or define a relationship between two variables. It is a measure of linear relationship between two quantities. A positive correlation means that an increase in one quantity leads to an increase in another quantity A negative correlation means with increase in one quantity the other quantity decreases.

We know that the older is the car the less is the resale value.

Thus, we can write that as the age increases, the resale value decreases. Thus, with increase in one variable, the other variable decreases.

Thus, there is a negative correlation between the cars age and the resale value.

Thus, the slope will have a decreasing trend.

Option A) The trend line slopes downward from upper left to lower right, so there is a negative correlation between a car’s age and its resale value.
