A pharmaceutical company is conducting a clinical trial to test the effectiveness of a new drug designed to lower blood pressure. H0: the new drug has no effect on lowering blood pressure. Ha: the drug does have an effect. A Type II error in this context would occur if the drug actually does have an effect on lowering blood pressure, but the study fails to reject the null hypothesis and concludes that it doesn't. What can be done in order to reduce the risk of Type II error? A. Choose a smaller significance level (for example, 0.01 instead of 0.05) B. Recruit more participants from urban areas with access to advanced healthcare facilities C. Increase the sample size D. Decrease the sample size
