Timber salvage is commonly done following a natural disturbance, to recover some value from the damaged forest. On public lands, salvage decision-making is complicated by the impact of this activity on a suite of ecosystem services that are valued by a wide variety of people. The U.S. Forest Service wants to know if there is evidence to indicate that the proportion of subjects in each group who is satised with their handling of salvage sales is different across the 4 main areas of this country. Test the claim that at least one of the proportions is different. Select the correct pair of null and alternative hypotheses. ' " Ho: At least one of the proportions is different from the others. H1: The proportions are the same across all the groups. ' " Ho! D1 = P2 H1391 D2 ' ' Ho: The mean number of subject who is satised is the same across all the groups. H1: At least one of the means is different from the others. ' ' H0: H1 = H2 H1411 #3 H2 Ho: The proportions are the same across all the groups. H1: At least one of the proportions is different from the others
