The net weight of packaged potato chips from a Philippine Food Conglomerate averages 95 grams with a standard deviation of 5% of the mean. Packed potato chips are considered underweight if they go below 86 grams. Suppose that the Conglomerate's quality control test is to randomly pick 7 packs of this potato chip from the processing line each hour and carefully weigh each pack's net weight. If 2 packs or more are underweight then the production process is stopped, to undergo recalibration. What is the probability that production is stopped due to this underweight quality control rule?
