(1 point) The purpose of this question is to compare the variability of 351 and $2 with the variability of (1 7:2). a) Suppose the first sample of 100 observations is selected from a population with mean ,ul = 200 and variance 0'12 = 800. Construct an interval extending 2 standard deviations of 151 on each side of m. S [41 S b) Suppose the second sample of 100 observations is selected from a population with mean ,u2 = 200 and variance 0'22 = 1030. Construct an interval extending 2 standard deviations of 762 on each side of pig. S2
