Research Hypothesis EssayNull Hypothesis The new positive drug has no considerable difference from the standard multi-drug authorities used by most crabby person patients (1 = 2).Alternative Hypothesis The new substantial drug is considerably better from the standard multi-drug regimen used by most cancer patients (1 2).The dependent variable in the study is the questionable level of efficacy (or in simple term, the level of effectiveness of the drug). This independent variable may be measured by 1) T-cell counts among AIDS patients, 2) improved blood circulation (measured by blood pumped per ounce per second), and 3) compute of antibody formation. For the sake of simplicity, we shall only consider the first measure of efficacy (T-cell counts among AIDS patients). The independent variable in the study is the type of drug used to treat patients with AIDS.MethodFor the purpose of theoretical efficiency, we can pretend the existence of two groups. Group A is a population sam ple treated with the new developed drug. Group B is a population sample treated with the standard multi-drug regimen. Note that both drugs atomic number 18 assumed to have a general effect on the mitigation of AIDS among patients. A high population mean (measured by T-cell counts) would indicate a higher level of efficacy.BiasesExperimenter preconception may be exhibited in the study as 1) error in the specification of experimental maneuver, 2) error in the measurement of outcomes, and 3) faulty interpretation of data. Because of the complexity of the study, it is very likely for the researcher to commit the second error. Selection bias is not present in the study.Ethical IssuesThere are two pressing ethical issues in the study. First, it is generally unethical to use an untested drug (medical) to a group of AIDS patients (although it may be argued that the drug has been tested many times in the laboratory). Second, it is dangerous to test the efficacy of two sets of drugs to g enuine patients.
