Fast food The global survey we learned about inExercise 35 also asked respondents how they felt aboutthe statement “I try to avoid eating fast foods.” Therandom sample of 800 included 411 people 35 yearsold or younger, and of those, 197 agreed (completely orsomewhat) with the statement. Of the 389 people over35 years old, 246 people agreed with the statement. Isthere evidence that the percentage of people avoiding fastfood is different in the two age groups?
