Here are some monthly cell phone bills, in dollars, for college students:

a. Convert these data from scale to ordinal. (Don’t forget to put them in order first.) What happens to an outlier when you convert these data to ordinal?

b. Roughly, what shape would the distribution of these data take? Would they likely be normally distributed? Explain why the distribution of ordinal data is never normal.

c. Why does it not matter if the ordinal variable is normally distributed? (Hint:Think about what kind of hypothesis test you would conduct.)
