Fig. 39.12 shows the frequency histogram of elite male 100 m sprint times up to 2002. Based on the histogram, write a short description of the most important features of the distribution, and draw a rough sketch of the PDF and CDF curves for the underlying distribution of elite male sprint times. Your sketches need only be rough, but you should try to give plausible values along the horizontal and vertical axes for each curve. Also explain why the vertical axis for the PDF curve must extend higher than 1.

Sprint times are often measured to very high precision, e.g., 0.001 s.

The official precision is 0.01 s, which is one hundredth of a second.
