Problem Set 1: A neuropsychologist assesses the cognitive functioning of 17 adults who are at-

than 24 indicate better cognitive functioning, while scores lower than 24 indicate worse
functioning and possible early-stage Alzheimer’s disease. The scores are contained in the table
below. Remember to put your initials within any and all variable names.
