a. Identify the relevant variable and parameter. A. The relevant variable is the population proportion, p, those for whom garlic is more effective than placebo. The parameter is whether garlic or placebo is more effective. B. The relevant variable is whether garlic or placebo is more effective, and the parameter is the population proportion, p, those for whom placebo is more effective than garlic. C. The relevant variable is whether garlic or placebo is more effective, and the parameter is the population proportion, p, those for whom garlic is more effective than placebo. b. State hypotheses for a large-sample two sided test. A. Ho: p<0.5 B. Ho: p=0.5 Ha: p=0.5 Ha: p<0.5 Z= D. Ho: p=0.5 H₂: p=0.5 E. Ho: p > 0.5 Ha: p=0.5 Check that sample size guidelines are satisfied for that test. No, the sample size was not large enough to make the inference. Yes, the sample size was large enough to make the inference. c. Find the test statistic value. (Round to two decimal places as needed.) C. Ho: p=0.5 Ha:p>0.5 F. Ho: p=0.5 Ha: p=0.5
