(a! What kind of plot makes a power law look iike a line? How is the slope of that line related to the power law? (b) Is the mean or the median more sensitive to outliers? (c) Presuming the statistical uncertainties of an experiment follow a Poisson distribution, by what factor does the statistical uncertainty decrease by if one obtains four times as much data? (d) Assume that an experimentat quantity is taken from a Gaussian distribution. How does the uncertainty in the mean scale with the number of observations, N
