Restrooms in the Park

APSTAT-110SGV

A large neighborhood association is considering adding a small restroom building to its three neighborhood parks and will choose a random sample of residents to ask their opinions.

The association decides to sort the neighborhood homes into two groups: those located near one of the parks and those not located near a park. The association will then randomly choose 10 homes from each of those groups.

Which of the following statements is false?

A

The homeowner's association stratified on the locations of the homes to guarantee equal representation of opinions from both groups.

B

The homeowner's association stratified on the locations of the homes to make the surveys easier to collect.

C

The homeowner's association stratified on the locations of the homes because that is a characteristic that could have an effect on people's opinions about the bathrooms.

D

The homeowner's association stratified on the locations of the homes so that it can compare the opinions of one group to the other.

E

The homeowner's association stratified on the locations of the homes to reduce variability in the difference between the two sample proportions.
