Tests with One Sample, Discrete Outcome" (Involves total & 3 categories: Total of people, how many exercise a lot, moderate and how many don't)

-I want to use chi square to shift in the distribution of responses to the exercise question. (test statistic)

-H0: represents the "no change" or "no difference" situation.  
-H1: H0 is false

-Data involves: total students, who exercises and who doesn't
-Either create a survey or investigate for a larger value from already created survey online
