a) Make a histogram of the data using a bar width of $20.
b) Make a histogram of the data using a bar width of $10.
c) Make a relative frequency histogram of the data using a bar width of $10.
d) *Make a stem-and-leaf plot of the data using $10 as the stems and putting the smallest amounts on top and round the data to the nearest $.
