Facebook considers someone a 'regular user' if they log on to their Facebook page at least three times per week. In a survey of college students, 729 out of 900 women surveyed said that they log on to their Facebook page at least three times per week. 616 out of 800 men surveyed said that they log on to their Facebook page at least three times per week. a) Make a 90% confidence interval for how much more likely women are to spend at least three hours per week than men. b) Explain how you can use this confidence interval to predict whether a hypothesis test will show that women in college are more likely to spend more than 3 hours a week on Facebook than men. c) Perform the hypothesis test which will answer the following question: Does this data provide statistically significant evidence that women in college are more likely than men in college to spend at least 3 hours a week on Facebook?|

Facebook considers someone a 'regular user' if they log
on to their Facebook page at least three times per
week. In a survey of college students, 729 out of 900
women surveyed said that they log on to their
Facebook page at least three times per week. 616 out of
800 men surveyed said that they log on to their
Facebook page at least three times per week.
a) Make a 90% confidence interval for how much more
likely women are to spend at least three hours per
week than men.
b) Explain how you can use this confidence interval to
predict whether a hypothesis test will show that women
in college are more likely to spend more than 3 hours a
week on Facebook than men.
c) Perform the hypothesis test which will answer the
following question:
Does this data provide statistically significant evidence
that women in college are more likely than men in college
to spend at least 3 hours a week on Facebook?|
