The tables that follow report the marital status of 20 respondents in two different apartment complexes. (HINT: Make sure that you have the correct numbers in the numerator and denominator before solving the following problems. For example, problem 2.1a asks for “the percentage of respondents who are married in each complex,” and the denominators will be 20 for these two fractions.

Problem 2.1d, on the other hand, asks for the “percentage of the single respondents who live in Complex B,” and the denominator for this fraction will be 4  6, or 10.)

Status Complex A Complex B Married 5 10 Unmarried (“living together”) 8 2 Single 4 6 Separated 2 1 Widowed 0 1 Divorced 1 0 20 20 SOC

a. What percentage of the respondents in each complex are married?

b. What is the ratio of single to married respondents at each complex?

c. What proportion of each sample are widowed?

d. What percentage of the single respondents live in Complex B?

e. What is the ratio of the “unmarried/living together” to the “married” at each complex?
