Persons having Raynaud'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 vater and the resulting heat output (cal/cm/min) vas measured. For m = 9 subjects with the syndrome, the average heat output was x = 0.62, and for n = 9 nonsufferers, the average output was 2.06. Let u and uz denote the true average heat outputs for the sufferers and nonsufferers, respectively. Assume that the two distributions of heat output are normal with a, = 0.1 and c, =n= What is the probability of a type II error vwhen the actual difference between , and uz is u - iz = -1.1? (Round your answer to four decimal places.) Assuming that m = n, what sample sizes are required ensure that 6 = 0.1 when u - uz = -1.1? (Round your answver up to the nearest whole number.)
