A hospital administrator wanted to know if the nurses at her hospital preferred one brand of stethoscope over another. She gave 3 nurses a different stethoscope to try out each week and asked them to rate their liking for that stethoscope on a scale of 1 to 5 (1 = hated it, 5 = loved it). Was there any difference in the nurses' preference in brand (α = 0.05)? Show all necessary components of a full hypothesis test, including a source table.
