In studying satisfaction patients have with an operation I have 2 random groups each given a different questionaire. I want to compare the responses of each group and see if the different percentage satisfied with their operation is statistically different depending on which questionaire they received. Total patients = 410 Group F 191 and had 170 satisfied Group S 219 and had 206 satisfied. What formula do I use to calculate if responses statistically different (p<0.5) between these groups please,
