2. A researcher for Netflix wants to know if people have different preferences for two shows: Friends and The Office. The researcher recruits 7 people. Each person watches five minutes of Friends and rates the show on a scale of 0-10, where 0 means they hate it and 10 means they love it. Then each person watches five minutes of The Office rates the show on a scale of 0-10. Assume that you are working at the .05 level of significance. The researcher obtains the following data:

Rating of The Office |

a gym), pop music, or hip-hop. Participants listen to their
respective tracks starting 2 minutes before an assistant waves
their arm to begin. The research assistant counts the number of
pushups each participant...
