Question. Find the mean, variance and standard deviation of the binominal distribution with the given values of n and p. N=126 , p=0.84 The mean u, is __ Round to nearest tenth The variance, o^2, is __ Round to nearest tenth The standard deviation o, is __ Round to nearest tenth Solution The mean u is n*p or 126*0.84 = 105.8 The variance n*p*(1-p) or 126*0.84*0.16 = 16.9 The stdev is sqrt of variance or sqrt of 16.9 = 4.1.
