◉ Before we continue on with the next steps of the scientific method
by continuing to look at this real world situation, try your hand at
formulating a hypothesis based on the following situation:
The premium gas at the pump is more expensive and you wonder if
this gas will improve your gas mileage.
Possible hypothesis:
The premium gas will improve the performance of your car.
The premium gas will improve the gas mileage of your vehicle as
compared to standard unleaded gas.
The premium gas is more costly
I wonder if the gas will make my car go further.
, Answer: The premium gas will improve the gas mileage of your
vehicle as compared to standard unleaded gas.
◉ Does the data in the table support our hypothesis?
