Two groups of patients were given two different types of pills – Pill A and Pill B. The percentage of headaches for each group were recorded as follows:

PILL A (pop1): x1 (yes)=1084 n1=11000 p̂1 =.0985

PILL B (pop2): x2 (yes)=997 n2=11000 p̂2 =.0906

Using a 5% level of significance, did patients who took Pill A suffer more headaches percentage-wise?
