An experiment was conducted to determine whether there is a difference between the success rates from treating carpal tunnel syndrome with surgery and with splinting. The success rate for 73 patients treated with surgery was 92%, and the success rate for 83 patients treated with splints was 72% (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). Discuss whether this difference appears to be statistically significant.
