According to the financial reports by Snapchat, the average daily user of Snapchat created 19 messages, or “snaps,” per day in Q3 2017. You want to find out if the number of Snapchat messages has changed since Q3 2017 and create a random sample using information from students on your campus for the current semester:

21          13          20          34          14          8             18          31          6             20

16          32          9             22          27          28          23          32          20          17

  1. Using α = 0.05, test the hypothesis that the number of Snapchats sent by the average Snapchat user has not changed since Q3 2017.
  2. What assumptions need to be made to perform this analysis?
