In a clinical trial of 73 carpal tunnel syndrome patients treated with surgery, 67 had successful treatments (based on data from “Splinting vs. Surgery in the Treatment of Carpal Tunnel Syndrome” by Gerritsen et al., Journal of the American Medical Association, Vol. 288, No. 10). What is the probability that the next surgery treatment will be successful?

Use the relative frequency method to estimate the probabilities in Exercises 31–34.
