Another group of researchers interested in the effects of sleep on the health of the brain looked at the concentrations of beta-amyloid proteins (a type of protein fragment that is suspected to play a role in the development of Alzheimer's disease) in the extracellular uid of the brains of rats under three conditions: three consecutive days of 6 hours of sleep per day (measurement 1); three consecutive days of 9 hours of sleep per day (measurement 2); three consecutive days of 12 hours of sleep per day. (Rats typically sleep about 12 hours per day.) Is there a difference in extracellular concentrations of beta-amyloid proteins in the rats under these three sleep conditions? Assume the data are Normally distributed. If there is a difference, please identify which measurement events are different from which other measurement events. Use the a-correction method with the greatest power.
