Doctors who received at least 85 percent of their practice income from managed-care plans were significantly less likely than other doctors to provide charity care. The phrase "significantly less" means that, when we compare the charity work of doctors with more than 85% of their practice in managed care with other doctors,... A...The difference in charity work is very large B... the differnce in charity work is less that we would expect just by chance in choosing a sample C...The differnce in charity work is so large that it would rarely occur just by chance in choosing a sample D...The difference in charity work is large enough to affect the doctors' income
