Own home	31	52	202	355	524
Rent home	67	66	52	23	11
Live w/ family	89	69	30	4	2

Find the marginal frequency for people who own their own home:

Find the marginal frequency for people who make less than $20,000 per year:

What proportion of people who make between $20,000 and $35,000 per year own their own home? Type your answer as a proportion (not a percent) rounded to the third decimal place.

Answer 1

SOLUTION:

	<$20,000	$20,000 -35,000	$35,000-50,000	$50,000-75,000	>$75,000	Total
Own home	31	52	202	355	524	1164
Rent home	67	66	52	23	11	219
Live w/ family	89	69	30	4	2	194
Total	187	187	284	382	537	1577

(a) The marginal frequency for people who own their own home = 1164

(b) The marginal frequency for people who make less than $20,000 per year= 187

(c) The proportion of people who make between $20,000 and $35,000 per year own their own home= 187 / 1577

= 0.118579   

= 0.119
