Question : 12 of 101

Marks: +1, -0

Interviewer: An alarming statistic reported in the Hobern Medical Journal is that 90 percent of the people in this country now report that they know someone who has heart disease.
Dr. Summer: But an expected level of heart disease is 5 percent, or in other words, 1 out of every 20 people. So at any given time if a person knows approximately 50 people, 1 or more will very likely suffer from heart disease.
Dr, Summer’s argument relies on the assumption that

Normal levels of heart disease are rarely exceeded
Heart disease is not normally concentrated in geographically isolated segments of the population.
The number of people who each know someone who suffers from heart disease is always higher than 90 percent of the population
The interviewer is not consciously distorting the statistics he presents
Knowledge that a personal acquaintance has heart disease generates more fear of getting heart disease than does knowledge of heart disease statistics.
