A clinical psychologist wants to explore a between-subjects experiment comparing treatments for PTSD emotionally focused therapy (EFT), client centered therapy (CCT), cognitive processing therapy (CPT), and cognitive behavioral therapy (CBT) against a control condition. Subjects were randomly assigned to the experimental condition. After 8 weeks, the subject's scores were measured using Treatment Outcome Post-traumatic Stress Disorder Scale (TOP-8). Identify which statistical analysis is appropriate for this data. Identify the IV and DV and their respective levels if applicable. Is this a repeated measures design?
4. Chantix (varenicline) tablets are used as an aid to help people stop smoking. In a clinical trial, 129 subjects were treated with Chantix twice a day for 12 weeks, and 16 subjects experienced abdominal pain (based on data from Pfizer, Inc.)If someone claims that more than 8% of Chantix users experience abdominal pain, that claim is supported with a hypothesis test conducted with a 0.05 significance level. Using 0.18 as an alternative value of P, the power of the test is 0.96. Interpret this value of the power of the test.

A researcher looking for evidence of extrasensory perception (ESP) tests 1000 subjects. Forty-three of these subjects do significantly better (P < 0.05) than random guessing. Forty-three seems like a lot of people, but you cannot conclude that these 43 people have ESP. Why not? The statistical significance level is not be stringent enough to conclude an ESP status. Since the tests were performed at the 5% significance level, as many as 50 subjects may have done significantly better than random guessing just by chance. The sample size was not large enough for any statistical inference. The P-value needs to be below 0.025 to be considered statistically significant given the two-tailed nature of this type of test.
