Question: For the following data obtained from three independent samples, use the 0.05 level in testing H0: 1 = 2 = 3 versus H1: At least

For the following data obtained from three independent samples, use the 0.05 level in testing H0: π1 = π2 = π3 versus H1: “At least one population proportion differs from the others.”
n1 = 100, p1 = 0.20
n2 = 120, p2 = 0.25
n3 = 200, p3 = 0.18
