a. Before drawing any graphs. try to visualize what the distribution of penny ages will look like. Will it be mound-shaped, symmetric, skewed right, or skewed left?
b. Draw a relative frequency histogram to describe the distribution of penny ages. How would you describe the shape of the distribution?
