Set up a hypothesis test to try to show that the mean number of hours studied by marketing majors at your school is different from the 12.1-hour-per-week benchmark reported by The Washington Post. Match the followings concepts to their correct interpretations in the context of the question: Null hypothesis Alternative hypothesis Type I error Type II error A. The mean number of hours studied by marketing majors at your school is not different from the 12.1-hour-per-week benchmark reported by The Washington Post and you conclude that it is different. B. The mean number of hours studied by marketing majors at your school is different from the 12.1-hour-per-week benchmark reported by The Washington Post. C. The mean number of hours studied by marketing majors at your school is not different from the 12.1-hour-per-week benchmark reported by The Washington Post. D. The mean number of hours studied by marketing majors at your school is different from the 12.1-hour-per-week benchmark reported by The Washington Post and you conclude that it is not different.
