The water diet requires one to drink two cups of water every half hour from when one gets up until one goes to bed, but otherwise allows one to eat whatever one likes. Four adult volunteers agree to test the diet. They are weighed prior to beginning the diet and after six weeks on the diet. The weights (in pounds) are _-EE The goal is to test whether the water 'diet' leads to a mean weight loss.(Hint: the differences have the mean of 5.5 and the standard deviation 15.199) a) What is the null hypothesis? Let subscript 1 indicate the measurement before the diet, and subscript 2 the measurement aer six weeks. 0 Ho: )1 1-)? z = 5.5 O HO: pl-pZ = 5.5 O HO: x 1-2 2 = o O HO: |.I1-|12 = o Tries 0/1 b) The alternative hypothesis for this test will be: 0 Ha: i l-iZ > 5.5 0 Ha: pl-uz > 5.5 0 Ha: X l-X 2 > 0 0 Ha: p1-u2 > 0 0 Ha: pl-pZ
