Persons having Reynaud's syndrome are apt to suffer a sudden impairment of blood circulation in fingers and toes. In an experiment to study the extent of this impairment, each subject immersed a forefinger in water and the resulting heat output (cal/cm2/min) was measured. For n1 = 10 subjects with the syndrome, the average heat output was 0.93, while n2 = 10 non - sufferers, the average output was 1.16. The researchers have assumed that the heat outputs are normal with true standard deviations are 0.3 and 0.5, respectively for sufferers and non-sufferers. Do sufferers of Reynaud's syndrome a lower heat output than non-sufferer? (Use α = 1%)
