1. In plastic injection molding, temperature, time in mold, and injection pressure each play an important role in determining the strength of the part. At MAR Inc., experimenters are studying the effects on part strength when the temperature is set at either 250^o, 275^o, or 300^oF; the time in mold is either 5, 7, or 9 seconds; and the injection pressure is either 200, 250, or 300 psi. Create a table show the factors and their levels for this information.
