(a) This statement is correct. H0: TECH values have the same distribution in all groups. Ha: TECH values are systematically higher in some groups than in others. , The data do not show systematic differences in TECH values across resort sizes. (b) This statement is correct. H0: EFFCH values have the same distribution in all groups. Ha: EFFCH values are systematically higher in some groups than in others. , The data show systematic differences in EFFCH values across resort sizes. (c) The rank sum for the large resort size is much larger than expected under H0.
