Researchers ran a quality control study to evaluate the quality of plastic irrigation pipes. The study design involved a total of 24 pipes, with 12 pipes randomly selected from each of two manufacturing plants. The pipes were manufactured using one of two water temperatures and one of three types of hardeners. The compressive strength of each pipe was determined for analysis. The experimental conditions are as follows:
