Question:

A classic study by F. Thorndike on the number of calls to a wrong number appeared in the paper €œApplications of Poisson€™s Probability Summation€ (Bell Systems Technical Journal, Vol. 5, pp. 604€“624). The study examined the number of calls to a wrong number from coin-box telephones in a large transportation terminal. Based on the results of that paper, we obtained the following percent for the number of wrong numbers during a 1-minute period.

a. Construct a relative-frequency histogram of these wrong number data.
