Answer 1

3x2x2

Step-by-step explanation:

Based on the information provided within the question it can be said that this design is an example of a 3x2x2 factorial. This is because there are 3 different variables being tested. The first is the condition of the course which has wet, dry, or icy (3). Secondly is power steering, with or without (2). Lastly is with automatic or manual transmission (2). Hence the factorial 3x2x2.
