7.In revisiting Case Study 5.4, we quoted the original journal article as reporting that "for any vertex baldness (i.e., mild, moderate, and severe combined), the age-adjusted RR was 1.4 (95% CI, 1.2 to 1.9)." Interpret this result. Explain in words that someone with no training in statistics would understand. a)With 95% confidence we can say that men with any vertex baldness are at a higher risk of heart attack than men with no baldness; their risk is 1.2 to 1.9 times greater.

b)With 95% confidence we can say that men without baldness are at a higher risk of heart attack than men with any vertex baldness; their risk is 1.2 to 1.9 times greater.

c)95% of men without baldness are at a 1.2 to 1.9 times greater risk of heart attack than men with any vertex baldness.

d)95% of men with any vertex baldness are at a 1.2 to 1.9 times greater risk of heart attack than men with no baldness.

e)With 95% confidence we can say that men with any vertex baldness are at a higher risk of heart attack than men with no baldness; their risk is 1.4 times greater.
