Consider a simple experiment in which the goal is to measure what is presumed to be a constant signal in the presence of a background. For this example, assume that there is Gaussian noise on both the signal and the background. In the first part of this notebook assume that you make several measurements of the 'total' of 'background + noise', and then you make measurements of the 'noise' alone. The 'signal' will then be the difference between the 'total' and the 'noise.' For class on Tuesday execute the cells in this notebook, and then determine the value of the signal, with an uncertainty. (There is nothing new here -- I just want you to become familiar with the 'experiment.'
