Line 7:
* '''Rule 4''': The funnel moves directly over the last place a marble landed.
 
Apply the four rules to the set of 50 pseudorandom displacements provided as dxs and dys (e.g in the Racket solution) for the dxs and dys. '''Output''': calculate the mean and standard-deviations of the resulting x and y values for each rule.
 
'''Stretch goal 1''': Generate fresh pseudorandom data. The radial displacement of the drop from the funnel position is given by a Gaussian distribution (standard deviation is 1.0) and the angle of displacement is uniformly distributed.
 
'''Stretch goal 2''': Show scatter plots of all four results.
