In 2008, Hurricane Ike struck the Gulf Coast. Ike caused severe damage, including flood damage, roof damage, tree loss, power outages, and personal financial loss. To study Ike’s effects, a survey was conducted of the people living in the affected community.
Sampling method 1: A phone poll that called the first person on each page of a 300-page community phone book.
Sampling Method 2: Handed out surveys to every fifth person entering a local grocery store and library.
Total surveys were taken: 180
Total community population: 81,000
The first survey question asked about flood damage. From the survey, 20 people reported that their homes sustained some sort of flood damage. Using this information, calculate how many people in the community sustained flood damage from the hurricane.
