The third intern surveys people about their moods, then gives them the mood music and are told
to listen to it daily for a week. After a week, people who "did their homework" (= listened to the
mood music daily) are surveyed on their moods, using the same scale as the second intern. 10
people stick with the program for the full week:

Based on this survey, can the intern make the claim that the music improves people's
average mood by more than 1 on a 0-to-10 scale? For credit, your answer must be both correct
and consistent with your answer in part j.
n) Generate a 98% confidence interval regarding the average improvement of people who
listen to mood music. Round appropriately to the 0.01.
o) [Suppose you learn that, in the third intern's study, there were 34 additional people who
were given the CD, but didn't listen to it daily, so they were discarded from the survey. Make a

produced.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd2a2a734-2581-4945-8007-7b269403fc13%2Ff6c19b9a-90fe-485c-a8dd-7d5446dab020%2Ffn7akc8_processed.jpeg&w=3840&q=75)
