Question: Second, find the average of the 30 numbers in each of your 300 rows of data. This gives you 300 sample averages from your 9000 random numbers, where each average is based on 30 numbers. Make a histogram of these averages using the same bins used for the first histogram. (Incidentally, you would make these bins smaller if you were making only this histogram, but since we want to compare the two histograms we need to use the same x-axis scale.)
