Mathematics

In a recent study to determine how often people in different parts of the United States check the weather, a random sample of residents in New England and a random sample of residents on the West Coast were surveyed. The study found over 90% of people surveyed in New England checked the weather daily, while 70% of people surveyed on the West Coast did so. If the margin of error of both samples were the same, which of the following statements is best supported by the study's findings?

A.People in New England check the weather more often because the climate is colder than on the West Coast.
B.People in New England check the weather more often because there is more weather coverage on television than there is on the West Coast.
