A nutritionist wants to investigate whether her new diet will be effective in helping women aged 30-40 to lose weight. She will use a paired sample to determine whether the mean weight of women before going on this diet is greater than the mean weight of women after being on this diet for two months. Determine the null and alternative hypotheses for the proposed hypothesis test. O A. Let μ₁ denote the mean weight of women before going on this diet and let μ₂ denote the mean weight of women who have been on this diet for two months. The null and alternative hypotheses are Ho: H₁ H2 and Ha: H₁ H2. OD. Let μ₁ denote the mean weight of women before going on this diet and let μ₂ denote the mean weight of women who have been on this diet for two months. The null and alternative hypotheses are Ho: H₁ H2 and Ha: H₁ H₂

Question
A nutritionist wants to investigate whether her new diet will be effective in helping women aged 30-40 to lose
weight. She will use a paired sample to determine whether the mean weight of women before going on this
diet is greater than the mean weight of women after being on this diet for two months. Determine the null and
alternative hypotheses for the proposed hypothesis test.
O A. Let μ₁ denote the mean weight of women before going on this diet and let μ₂ denote the mean
weight of women who have been on this diet for two months. The null and alternative hypotheses
are Ho: H₁ H2 and Ha: H₁ <H2.
O B. Let μ₁ denote the mean weight of women before going on this diet and let μ₂ denote the mean
weight of women who have been on this diet for two months. The null and alternative hypotheses
are Ho: H₁ H₂ and Ha: H1 = H2.
O C. Let μ₁ denote the mean weight of women before going on this diet and let μ₂ denote the mean
weight of women who have been on this diet for two months. The null and alternative hypotheses
are Ho: H₁ H₂ and Ha: H₁> H₂.
O D. Let μ₁ denote the mean weight of women before going on this diet and let μ₂ denote the mean
weight of women who have been on this diet for two months. The null and alternative hypotheses
are Ho: H₁ H2 and Ha: H₁ H₂.
