Question 29

A homeowners association consists of 20 homes.The family in each home is considered an automatic member of the association.Recently,one of the homes fell into a state of disrepair.A survey was conducted of the homeowners both on the same street as the house in question and on the second street.At issue was whether legal action should be brought against the homeowner with the problem house.There are 8 homes on the same street as the problem house and 6 of these called for legal action.The percentage of houses on the second street that favored legal action is 50 percent.Which type of chart might be most effective for conveying the information about percentage of residents favoring legal action by street?
