The global survey we learned about in Exercise 41 also asked respondents how they felt about the statement I try to avoid eating fast foods. The random sample of 800 included 411 people 35 years old or younger, and of those, 197 agreed (completely or somewhat) with the statement.
Of the 389 people over 35 years old, 246 people agreed with the statement. Is there evidence that the percentage of people avoiding fast food is different in the two age groups?
