Wrong Number. A classic study by F. Thorndike on the number of calls to a wrong number appeared in the paper "Appli- cations of Poisson's Probability Summation" (Bell Systems Tech- nical Journal, Vol. 5, pp. 604-624). The study examined the num- ber 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 distribution for the number of wrong numbers during a 1-minute period.

Wrong 0 1 2 3 4 5 6 7 8

Percent 17.2 30.5 26.6 15.1 7.3 2.4 0.7 0.1 0.1

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

b. Based on your histogram, do you think that the number of wrong numbers from these coin-box telephones is approximately normally distributed? Explain your answer.
