A researcher is interested in whether regularly smoking marijuana would affect digit-span recall, which is a measure of short-term memory. The researcher first found two groups of participants (‘smoke_group’): (1) nonsmokers and (2) smokers. Each group was given a digit-span test, and the number of digits recalled is listed in the ‘digit_span’ column in the Data View. A higher digit-span score implies a better short-term memory. Question 6 (6 pts): Perform a statistical test to evaluate whether smoking marijuana affects digit-span recall.
