An article appearing in The Exponent, an independent college newspaper published by the Purdue Student Publishing Foundation, reported that the average American college student spends 1 hour (60 minutes) on Facebook daily. In order to test the validity of this statement, you select a sample of 30 Facebook users at your college. The results for the time spent on Facebook per day (in minutes) are stored in the excel workbook named Facebook Time.

b. What assumption about the population distribution is needed if the sample size is smaller than 30?

c. Make a list of the various ways you could evaluate the assumption noted in (b).
