Explanation / Answer

There are several categories of people who live w/family, 5 categories to be precise.

The value in each cell gives the value corresponding to that level of the two variables given,

eg, here , the two variables are 1. the living status and 2. the annual household income

So, corresponding to all the levels of the annual household income, we add the values for "Live w/family".

We get the row total =89+69+30+4+2=194

This is the total number of people who live w/family.

So, number of people who live w/family as well as earn between $35-50,000= 30

Therefore the required percentage = ( number of people who live w/family as well as earn between $35-50,000) /(total number of people who live w/family.) *100

=30/194*100 %

=15.4639175 = 15.464 % approx.

So ,correct option is : C

<$20,000 $20-35,000 $35-50,000 $50-75,000 >$75,000 row 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
