Are anesthesiologists overworked and therefore putting patients at risk? This question was investigated as part of a survey carried out at the University of Florida. The population of those practicing anesthesiology was stratified into three groups: anesthesiologists (composing approximately 50% of the population), anesthesiology residents (composing approximately 10% of the population), and nurse anesthetists (composing approximately 40% of the population). The frequencies of those in each stratum who thought they had worked without a break beyond a safe limit sometime during the last 6 months are shown in the accompanying table:
Â

Â
a. Estimate the population proportion of those who think they have worked beyond a safe limit. Calculate a bound on the error of estimation.
Â
b. Do anesthesiologists differ significantly from residents in this matter?
Â
c. Do anesthesiologists differ significantly from nurse anesthetists in this matter?
