Some people have suggested that Alzheimer disease may be at least partially caused by a contagious agent. If this were true, one might expect that people who come into contact with brain tissue may be more likely to be exposed to such contagion. Lollis et al. (2010) found that 14 of 7163 male neurosurgeons contracted Alzheimer disease during a 26-year study. The probability of Alzheimer disease in the general population of males of the same age group is 0.00084. Give a 95% confidence interval for the proportion of neurosurgeons who contract Alzheimer disease and interpret this result in the context of the rate expected in the general population.
