59. Simulations Use your statistical software to draw a random sample of 30 observations from a standard Normal distribution (look for menu items like Random and Normal and plug in 0 and 1 for the parameters). Plot the data in a histogram and in a Normal probability plot.

a) Compare the two plots. Is it easier to judge bellshapedness or straightness?

b) Repeat four more times, and answer the same question. Is it easier to be fooled by the purely random squiggles in the data when viewing the NPPs or the histograms? Or put another way, in which type of plot is it easier to see the essential pattern through the noise or random jitter?
