You plan to test the dependent sampling claim: "a particular weight loss program is effective in weight reduction." What would be the null hypothesis, if d=X after −X before?
A) Ho: μd = 0
B) Ho: μd = 0 (≥)
C) Ho: μd ≠ 0
D) Ho: μd = 0 (≤)
This solution determines the null hypothesis for a dependent sampling claim.
