A researcher believes that the proportion of trees affected by beech bark disease is different between stands growing in better drained soils compared to stands growing on more poorly-drained soils. Use the following data to test his claim Select the correct pair of null and alternative hypotheses. Better-drained sites Poorly-drained sites x1 = 114 X2 = 97 n1 = 451 n2 = 189 OHo: P1 = P2 H1: P1 * P2 OHo: P1 = P2 H1: P1 P2 OHo: H1 = H2 H1: H1 * H2 OHo: H1 = H2 H1: M1
