What is a percentage?

The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:

$P = \frac{a}{b} \times 100\%$

Of the 38 people in houses, 17 have dogs, hence the percentage is given by:

pH = 17/38 = 44.74%.

Out of all residents, the percentage is given by:

pA = 21/66 = 31.82%.

The percentage in houses is considerably greater than for all residents, hence the statement that explains the positive association is given by:

There is a positive association because the percentage of residents living in a house that have a dog is greater than the percentage of all residents who have a dog.
