1. 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 p 1 =.0985 PILL B (pop2): X2 (yes)=997 n2=11000 p 2 =.0906 Using a 5% level of significance, did patients who took Pill A suffer more headaches percentage-wise? 2. A study was conducted to find out whether waiters (pop1) or waitresses (pop2) earned different amounts of tips. A waiter and a waitress were selected to record their tips in 50 different restaurants. The mean of the sample differences was -$1.16 and the standard deviation of the sample differences was $2.22. Using a 5% level of significance, can we conclude that waiters and waitresses earn significantly different amounts of tips? Assume matched pairs
