Question
Q. The hippocampus shrinks in late adulthood, leading to impaired memory and increased risk for demen- tia. In a study of evaluating whether exercise training expands the hippocampus and improves spatial memory, 60 healthy but sedentary participants, aged 58 to 70, joined a one-year aerobic exercise pro- gram. Magnetic resonance images were collected before the intervention and again after the completion of the program and participants’ hippocampal volumes (in cm3) were measured.
(a) Does exercise training increase the average size of hippocampus by more than 0.1 cm3? Give a test at 5% level of significance.
