Reference no: EM13629501

Researchers were interested in the relationship between age and brain activity. They collected data on 20 subjects using an electroencephalogram (EEG), a device that measures electrical activity in the brain. Data from the EEG are ordinal in nature. Given those data below, are we justified to conclude that brain activity decreases with age? Show all steps in work.
