Exergames are active video games such as rhythmic dancing games, virtual bicycles, balance board simulators, and virtual sports
simulators that require a screen and a console. A study of exergaming practiced by students from grades 10 and 11 in Montreal,
Canada, examined many factors related to participation in exergaming. 23 Of the 358 students who reported that they stressed
about their health, 29.9% said that they were exergamers. Of the 851 students who reported that they did not stress about their
health, 20.8% said that they were exergamers. Find the 95% confidence interval for the difference in proportions. Give your answer as an interval in the form (lower bound,
upper bound). Give your numbers for each bound to four decimal places.
95% confidence interval:
A. There is 95% confidence that among Canadian youth in 10th and 11th grades, between 4% and 15% more youths who
do not stress about their health are exergamers than those who stress about their health.
B. There is 95% confidence that among Canadian youth in 10th and 11th grades, about 9% fewer youths who do not stress
about their health are exergames than those who stress about their health.
C. There is 95% confidence that among Canadian youth in 10th and 11th grades, between 4% and 15% fewer youths who
do not stress about their health are exergamers than those who stress about their health.
D.There is 95% confidence that among Canadian youth in 10th and 11th grades, between 4% and 15% more youths who
stress about their health are exergamers than those who do not stress about their health.
