There is some concern that exposure to gases used in anesthesiology may be harming the health of anesthesiologists. In one study of 525 Michigan nurse anesthesiologists, 10 reported a new malignancy other than skin cancer during the previous year.

What is the appropriate choice of distribution for the incidence of new malignancies in this study?

What is the best estimate of the incidence rate of new malignancies from these data?

Provide a 95% confidence interval for the true malignancy rate.

The overall rate in Michigan for people of the same age distribution was 402.8/100,000 person-years. Did the nurse anesthetists show a higher rate than the general population?
