1. The problem statement, all variables and given/known data You have run an experiment and generated a histogram. Suppose you had 853 counts in the bin centered at 1.60, and 2,439 counts in the bin centered at 1.85. If you were to repeat this experiment (by measuring the same source for the same time period, delta t) you know that you would measure a somewhat different number of counts in each of these two bins. Estimate the experimental uncertainty in the measured number of counts for each of these two bins. In other words, estimate how much your measured number of counts (853 or 2,439) might differ from the true average number of counts in each bin. 2. Relevant equations I don't know what the relevant equation is... I guess that's part of the problem. 3. The attempt at a solution I don't know where to start with this, any help or advice you can give me is very welcome.
