Do children feel less pain than adults? That question was addressed by nursing professors at the University of Alberta and the University of Saskatchewan. Suppose that in a preliminary study, 50 8-year-old children and their mothers were subjected to moderately painful pressure on their hands. Each was asked to rate the level of pain as Very severe (4), Severe (3), Moderate (2), or Weak (1). The data were recorded using the codes in parentheses. Can we conclude at the 1% significance level that children feel less pain than adults?
