	a) Find the marginal distributions of their previous viewing of the movie. Margin means total. Create a new column labeled "total".
	b)Verify that the marginal distribution of the ages is the same as that given previously. Create a bottom row labeled "total".
18	Continue with the data from question 17
	c) Find column percentages.
	e) Make a stacked bar chart showing the distribution of viewings for each age level
	f) What is the percentage of all audience members who are over 21? And what percentage of audience members who saw the movie more than once are over 21?
	g) If these proportions are not the same, what does that mean with respect to the variables "age" and "frequency of viewing movies"?
