Question

10. Suppose you were to collect data for the following pair of variables, gasoline: number of miles driven since your last fill up, gallons of gas remaining in your tank. You want to make a scatterplot. Which variable would you use as the explanatory variable? number of miles driven since your last fill up gallons of gas remaining in your tank Which variable would you use as the response variable? number of miles driven since your last fill up gallons of gas remaining in your tank · Would you expect to see a positive or negative association? positive negative neither

Explanation / Answer

The gallons of the gas remaining in the tank is dependent on the number of miles driven since last fill up. Higher the number of miles driven lesser wil be amount of gas left in the tank and vice-versa. So, explanatory variable would be number of miles driven since last fill up and response variable would be gallons of gas left in the tank. Also, we would see a negative association.
