If you were testing how well different automatic car washes cleaned carsthe control group would be?

The control group in this experiment would consist of cars that are cleaned using a standard method, such as hand washing or a basic car wash without any added features or treatments. This allows for a comparison to assess the effectiveness of different automatic car washes. By keeping the conditions consistent for the control group, any differences in cleanliness can be attributed to the specific automatic car washes being tested.
