The Women's Health Study Included 39,876 Female Health Professionals Aged

The Women's Health Study included 39,876 female health professionals aged 45 years and older who were followed for an average of 10 years (Ridker et al., 2005) . At the beginning of the study, participants were randomly assigned to take either a daily low-dose aspirin or a daily placebo pill for the duration of the study. At the end of the study, researchers measured the number of participants that suffered from a heart attack during the study. Data are summarized in the following table.
-Does there appear to be an association between whether a woman takes low-dose Aspirin or placebo and if she suffers from a heart attack in this sample?

A) No, since approximately the same number of women suffered from a heart attack in each group.
B) Yes, women who took low-dose Aspirin were less likely to suffer from a heart attack.
C) Yes, women who took low-dose Aspirin were more likely to suffer from a heart attack.
