Each child is asked which of the following TV programs they like best: The Lone Ranger, Sesame Street, or The Simpsons. Results are shown in the contingency table below. Overall, what percentage of the boys preferred The Simpsons? Overall, what percentage of the girls preferred The Simpsons? Looking at the table, do you think the boys’ preferences for these TV programs differ significantly from the girls’ preferences? a Yes, because more girls than boys participated in the survey. b Yes, because the difference in counts between the boys’ and girls’ preferences on Sesame Street and The Simpsons seem too far apart. c No, because my answers in part a and b are close. d No, because the totals for the Lone Ranger are both 50.
