Los Angeles County is located closest among the three to a major earthquake fault line. Are homeowners in Los Angeles County more likely to purchase earthquake insurance than those in San Bernardino County?
California insurance companies wanted to study factors (e.g.,
the proximity to a major earthquake fault line) that may influence
homeowners’ decisions to purchase earthquake insurance. Surveys
were mailed to randomly selected households in three California
counties to investigate the possible proximity effect. The data
collected are shown below:Sample size1000- Los Angeles1200- San Barnadino1400-Santa ClaraNumbers with earthquake insurance377-Los Angekes469-San Bernadino390-Santa Clara1. Los Angeles County is located closest among the three to a
