She randomly assigned newborn rats from a highly inbred line to one of three diets: (1) unlimited access to food, (2) 90% of the amount of food that a rat of that size would normally eat, (3) 80% of the amount of food that a rat of that size would normally eat. She maintained the rats on the three diets throughout their lives and recorded their life spans (in years). Complete a Turkey's post HOC test to determine which one is significantly different
