. For each of these panels, estimate l and compute the 95% confidence interval. In 95% of the K panels, the true value of l should lie within the confidence interval. For our simulation experiments we chose M = 400, that is, l~4 00 765 . We chose K = 70000. In Figure 5 we show the histogram of H which is really same as distribution of P scaled by a factor of 765. In Table 1 we show how the predicted values match with the actual simulation values. In the same way, the sampling distribution of number of molecules matched with what is predicted by theory. Though the results of the simulation follow from elementary probability, we conducted these simulations in order to build more advanced simulations for ratios of concentrations later. They also illustrate the meaning of the confidence interval.
