A recent study in the Journal of the American Medical Association reported the results of an experiment where 40 overweight individuals followed the Zone diet for one year. Their weight changes (original weight - ending weight) at the end of the year had a mean of = 3 kg with a standard deviation of s = 5.8 kg. We want to use this data to test the claim that the diet has an effect, that is, that the weight change is higher than 0. Q7.1 1 Point Which set of hypotheses should be used for testing this claim?
