Is smoking pot associated with trouble learning math? Researchers at the University of Iowa College of Medicine reported that students who smoked 2 or more marijuana cigarettes per week had lower math scores than nonmarijuana 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, 5:10). The null hypothesis was MPOT MNOPOT = 0' The 95% condence interval for the difference between the two means (-0.79, 10.79) is evidence that supports which of the following conclusions? 0 We can be 95% condent that there is a statistically signicant difference in average math scores between the two groups of students who were surveyed. Q There is a statistically signicant difference in average math scores between the two populations. 0 There is no statistically significant difference in average math scores between the two populations. 0 95% of nonmarijuanasmokers score better than 95% of those who smoke 2 or more marijuana cigarettes per week
