1) follow the example to demonstrate central limit theorem with 1000 row times 30 variables of with binomial distribution of p=0.5, n=1. Create the same statistics and generate the same set of two histograms. You need to adjust the bin size to optimize the look of the histograms. Post both histograms (1 point)

2)Can you tweak the excel sheet a little to convert this exercise into acomputer simulation of the mechanical Galton machine? (hint: just change the function of x-bar column from average to something else.)The difference is now we can increase the level and number of balls to a much larger number, and adjust p to any value. Try a few different parameter values. Describe what you do & post a histogram thatthat shows a computer simulation ofthe Galton machine. (1 point)
