Answer: 1%

Explanation:

Add up the frequencies in the bottom row: 350+200+245+125+66+10+4 = 1000

There are 1000 families total. Of this total, 10+4 = 14 families have more than six people. I added up the frequency counts for "7 people" and "8 people" to get 14.

Divide 14 over 1000 and we get 14/1000 = 0.014 = 1.4% which rounds to 1%
