Nonresponse is a common problem facing researchers who rely on mail questionnaires. In the paper "Reasons for Nonresponse on the Physicians' Practice Survey" (1980 Proceedings of the Section on Social Statistics [1980]: 202), 811 doctors who did not respond to the AMA Survey of Physicians were contacted about the reason for their nonparticipation. The results are summarized in the accompanying relative frequency distribution. Draw the corresponding bar chart.
