Business faculty at a prestigious community college wanted to evaluate the infuence of Netflix on student academic performance. After careful consideration, the faculty decided to conduct a prelimary study to see if they could justify a more detailed analysis. The preliminary study follows:

Sixty (60) students were selected for two sections of a Business Adminstration class. The students were selected based on their previous performance in an introductory level course. In order to enroll in one of the sections, students had to earn an 85 or higher in the introductory course.

The students in Section 1 agreed to spend at least 15 hours per week preparing for class. During the 15 hours, the students were required to work either in the library or a comparable, on-campus study location that was completely free of distractions (i.e., no smartphones, musical devices, or any other digital media).

The students in Section 2 were given free, unlimited access to Netflix and encouraged to use their account as much as possible when not preparing for class. The students were not required to spend any time preparing for class.

Both sections were taught by the same professor using the same materials. Great care was taken to insure that both classes received approximately the same course content at the same time.

The following data shows the test scores for each student on the first test:
