Question 35 2 pts Researchers examined whether smoking impairs memory function. They recruited a group of participants (n = 49) with a history of smoking (>20 years) and assessed their memory. In one test, the participants were asked to listen to a list of words and then to repeat them back. The adult population can repeat back an average of 7 words with a standard deviation of 2.20 words (i.e., 11=7; 0=2.20). At the conclusion of the study the researchers reported that post-hoc power of the study was 48% at the 5% alpha-level. Which of the following is the least likely to be true for this study? this is a one-tailed test. O O p=O.04 M=6.46 (sample mean) O SD = 1.8 (sample standard deviation) O critical value of the relevant test statistic is 1.65. O
