The real question should perhaps become: "is it really a random error?"
When you take most probablility and statistics courses, you spend the semester considering only proper statitical problems. However, when the probability gets too low, maybe it is time to think different thoughts. i.e. if you roll a dice (without looking too closely at it), and you get a 5 twenty time in a row, perhaps it is time to inspect the dice more closely!! You are more likely to have a loaded dice than to have actually rolled the same number 20 times at random.
Here, there may well have been a production glitch that comparably affected a bunch of machines.
