Is there a linear relationship between the speed at which a car is driven and the gas mileage? A car was driven on a test track for one hour at each of 5 speeds and the gas mileage calculated. Here are the results:
Km/Hour |
Km/Liter |
30 |
24 |
50 |
28 |
70 |
30 |
90 |
28 |
110 |
24 |
Draw a scatterplot and determine whether there appears to be a linear relationship between speed and gas mileage. If so, describe the relationship, calculate r, and determine what percentage of the variability in the gas mileage can be explained by the variability in the speed.
Can you suggest any alternate options? Why?
