Rephrase this question in terms of a sample mean value. The following was taken from an Associated Press report published in the Des Moines Register on February 15, 1999. A new study adds to evidence that the eating disorder bulimia springs at least in part from a chemical malfunction in the brain. In the study, women who had suffered from bulimia and had recovered were more affected psychologically than other women by being deprived of tryptophan, an amino acid that occurs naturally in many foods and plays a role in regulating appetite. Compared to normal women, the recovered bulimics reported bigger dips in mood, greater worries about body image and more fear of losing control of eating after being deprived of dietary tryptophan for about 17 hours.
