Question

the table lists weights (pounds) and highway mileage amounts (mpg) for seven automobiles. use the sample data to construct a scatterplot. use the first variable for the x - axis. based on the scatterplot, what do you conclude about a linear correlation?
weight (lb) 2745 2990 3210 3965 4035 2230 3190
highway (mpg) 34 33 30 26 24 38 31
which scatterplot below shows the data?
a.
b.
c.
d.

Explanation:

Step1: Identify x - and y - variables

The weight (in pounds) is the x - variable and the highway mileage (mpg) is the y - variable.

Step2: Analyze the relationship trend

As the weight of the automobiles increases, the highway mileage generally decreases. For example, when weight goes from 2230 lb (with 38 mpg) to 4035 lb (with 24 mpg).

Step3: Match with scatter - plot

We are looking for a scatter - plot where the points generally go downwards from left to right.
