lem #1: A research firm is interested in determining if the blood cholesterol level of a specific sub-population of senior citizens has become higher over recent years. In the past, this sub-population was believed to have an average blood cholesterol level of 120 mg/DL. They collect data on a sample of 1155 seniors from this population and find their average blood cholesterol level is 138 mg/DL and their standard deviation is 3.5 mg/DL. What are the null and alternative hypotheses? (A) Ho:μ = 138 vs Hau > 138 (D) Ho:x = 120 vs Ha:x < 120 (G) Ho: 120 vs Ha: (B) Ho: < 120 vs Ha> 120 (C) Ho: < 138 vs H₂ : > 138 (E) H₁ μ = 120 vs Ha: <120 (F) Hoμ = 138 vs Ha:μ< 138 120 (H) Ho:* = 138 vs Hax< 138
