Question 5.35
5. Suppose that you and your friends emptied your pockets of coins and recorded the year marked on each coin. Would you expect the histogram for the distribution of dates to be skewed to the left or right? Explain your answer and make a sketch of this histogram.
5.
Most coins in circulation were minted in recent years, so we would expect a peak at the right (highest-numbered years, like 2012 and 2014) and lower bars trailing out to the left of the peak. There are few coins from 1990 and even fewer from 1980, etc.
