Assume that two dependent samples have been randomly selected from normally distributed populations. The table below shows the weights of seven subjects before and after following a particular diet for two months. Subject A B C D E F G Before 157 160 156 183 190 157 161 After 150 151 154 188 176 159 149 Using a 0.01 level of significance, test the claim that the diet is effective in reducing weight.Write the claim for the above problem O HO: ud = 0 H1: ud > 0 O HO: ud = 0 H1: ud # 0 O HO: ud = 0 H1: ud
