Those 4 are the possible answers

phat = 81/368 = 0.2201086957 ≈ 0.22 q = 1 - 0.2201086957 = 0.7798913043 = 0.78 P(0.22 - 1.96*sqrt(0.22*0.78/368) < π < 0.22 + 1.96*sqrt(0.22*0.78/368) ) = 0.95 P(0.22 - 0.04 < π < 0.22 + 0.04) = 0.95 P(0.18 < π < 0.26) = 0.95 sample proportion = 0.18 margin of error = 0.04
