Identify the hypothesis in the following argument; and, if it fails to meet the four criteria for good scientific hypotheses, state which criterion is violated, and explain your answer.
A local refrigerator manufacturer has been experimenting with new designs for vegetable bins, suspecting that humidity level was a critical factor in the length of time vegetables stay fresh. The first design maintained a humidity level of 10 percent but the vegetables shriveled in a fairly short time. Another design maintained a humidity level of 60 percent but the vegetables began to rot in less than two days. The third design tested maintained a humidity level of 28 percent. The vegetables in this bin stayed fresh for five days, much longer than the industry standard of three days. The manufacturer concluded the experiments, satisfied that optimum humidity level is critical for maintaining the freshness of vegetables as long as possible.
