1. (3 pt)  Using the Random walk simulation available on the class web site, find the full width at half maximum (FWHM) of the distribution of walk lengths when the number of steps equals and 5, 25, 100, 225.  Run at last 1000 trials for each case.  Plot the FWHM versus number of steps and see if you can find an approximate function form describing the relation.  Note that the  full width at half maximum is defined as the number of walk lengths having a number of trials greater than half the maximum number of trials for any walk length.
