Explanation / Answer

p1=x1/n1=30/2197=0.0137

p0=x0/n0=27/1646=0.0164

Relative risk=p1/p0=0.0137/0.0164=0.835

Odds ratio=(p1/(1-p1))/(p0/(1-p0))=(0.0137/(1-0.0137))/(0.0164/(1-0.0164))=0.833

Right choice is D. The drug does not appear to pose a risk of headaches because p1 is slightly less than p0
