Researchers at a science corporation and a university collaborated on a study of how air traffic controllers respond to false alarms. The researchers theorize that the high rate of false alarms regarding midair collisions leads to the "cry wolf" effect the tendency for air traffic controllers to ignore true alerts in the future. The investigation examined data on a random sample of conflict alerts. Each alert was first classified as a "true" or "false" alert. Then, each was classified according to whether or not there was a human controller response to the alert. A summary of the responses is provided in the accompanying table. Do the data indicate that the response rate of air traffic controllers to midair collision alarms differs for true and false alerts? Test using What inference can you make concerning the "cry wolf" effect?
