The Behavioral Risk Factor Surveillance System is an ongoing health survey system that tracks health conditions and risk behaviors in the United States. In one of their studies, a random sample of 8,866 adults answered the question "Do you consume five or more servings of fruits and vegetables per day?" The data are summarized by response and by age-group in the frequency table below. Age-Group (years) Yes No 18-34 231 35-54 669 55 or older Total 1,291 2,191 741 2,242 3,692 6,675 Total 972 2,911 4,983 8,866 Do the data provide convincing statistical evidence that there is an association between age-group and whether or not a person consumes five or more servings of fruits and vegetables per day for adults in the United States? The value of the test statistic is 83.663. Use a 0.05 level of significance to test the hypothesis. The critical value is 5.991. What is the expected number of 19-34-year-olds who say that they consume five or more servings of fruits and vegetables per day? Among those in the 35-54-year-old age group, what is the probability of reporting having eaten five or more servings of fruits and vegetables per day? In the entire group, what are the odds in favor of reporting eating five or more servings of fruits and vegetables per day?
