The 2016 GSS also asked respondents about the type of schedule they worked. Out of 812 respondents who answered this question, 624 said they worked a regular schedule or shift (i.e., a "set" schedule). Does this provide evidence that over 75% of Americans work regular (or "set") schedules? Use the information provided to test the claim that over 75% of Americans work regular (or "set") schedules. Use alpha level = 0.05.
