Question 1012567: I have weighed an item numerous times over a long period of time and under different conditions (i.e. temperature, humidity, time of day, atmospheric pressure, etc.)and then calculated the mean and three standard deviations. Can I say that any time I would weigh this item there is a 99.7% probability the weight will fall within the three standard deviations I calculated?
