According to this, answer the following questions (in questions b, c and d, include all calculations): A. H0: ________ B. If, when planning the experiment, the researchers did not know whether the drug was expected to increase or decrease blood pressure: H1: ______; and, is the correlation significant at the fixed-level α = 0.05?C. If the researchers’ initial assumption was instead that the drug was expected to increase blood pressure (H1: ρ > 0), is the correlation significant at the fixed-level α = 0.05?D. If H1: ρ > 0, and α = 0.01, is the correlation significant?
