The margin of error is too high to say what the true value is (or should be), but in no way does that imply that the true value should be ZERO.  A small number does not automatically mean zero.<p>You could make up similar lies and say that &quot;statistically, the amount of lead in your drinking water is zero&quot;, and have it be well less than 12 parts in 10,000, and it&#x27;s still non-zero, and at neurologically toxic levels.  Just because a number is small does not mean that we cannot accurately measure it, nor does it mean that the expected value is zero.  Claiming that the expected value is zero when there are twelve in your (large) sample is a horrible misuse of statistics.
