Question: Does lecithin enhance memory? To test this idea, nine pairs of people matched in terms of age, sex, IQ and neurological status are given capsules containing either lecithin or a placebo at meals for a week. All are scored on a recent memory talk. A higher score indicates better task performance.

1. Conduct and interpret the appropriate analysis to determine if lecithin significantly improved memory. (5 pts)
2. Create the appropriate graph to show the difference between the two treatment approaches. (2.5 pts)
3. People scoring below the 35 ^th percentile in the Placebo group are going to be ‘tagged’ for further assessment. What score would alert researchers to the need for such assessment?
4. After review of the scoring and assessment tool, researchers decided that equal intervals could not be assumed, and that the data should be treated as a rating. Conduct and interpret the appropriate analysis to determine if the lecithin group has significantly better memory. (5 pts)
