Question 9 3 pts Is smoking pot associated with trouble learning math? Researchers at the University of lowa College of Medicine reported that students who smoked 2 or more marijuana cigarettes per week had lower math scores than non-marijuana users. The mean math score for those who did not smoke marijuana was 74% (n=42, s=12) and the mean math score for those who smoked 2 or more marijuana cigarettes a week was 69% (n=24, s=10). The null hypothesis was UPOT - UNOPOT = 0. Using alpha of 0.05, researchers also calculated a test statistic of 1.74 (p=.07) for these results. Based on these results, could the researchers have committed a Type I Error or a Type II Error? O We cannot tell which type of error might have been made from the information given. The results could have been a Type I Error because they failed to reject the null hypothesis. If there actually is a difference between the two groups, the researchers did not detect it. O The results could have been a Type II Error because they failed to reject the null hypothesis. If there actually is a difference between the two groups, the researchers did not detect it.
