A manufacturer of automatic car transmissions uses steel gears. An important characteristic of these geras is their hardness. An experiment is conducted to compare gears made from three different steel alloys, that is, three is, three different compositions of steel. Gears made from each of these steel alloys were heat-treated or hardened at two different temperature levels, and . Twelve gears of each of the three different steel alloys were available--six were randomly assigned to each of the two temperature levels. For this experimental situation:
1. How many different treatment combinations will there be?
2. Create the design table and how many total experiment units will be needed for this experiment?
