Researchers want to test the effectiveness of a new anti-anxiety medication. three hundred eighty patients were recruited to participate in the clinical trial and were randomly assigned to two groups, of which one received the medication, and the other, a placebo. in clinical testing, 64 out of 200 people taking the medication reported symptoms of anxiety. of the other 180 people receiving a placebo, 88 reported symptoms of anxiety. do you think if the patients in the two groups performed significantly different with respect to symptoms of anxiety? use 0.05 as the level of significance. (hint: use 1.96 and -196 as the critical z-values).
