Expert Solution

Part 1

The homes that were surveyed larger than 4000 square feet come under the interval of 4000-5000 feet, 5000-6000 feet,6000-7000 feet, and 7000-8000 feet, for which the corresponding frequency values are 20,20,5,5, respectively.

By simply adding all the frequency values, i.e. $20 + 20 + 5 + 5 = 50$ is the required number houses those were larger than 4000 square feet.

So for "About how many homes surveyed were larger than 4000 square feet" the answer would be 50.
