The cumulative frequency function of a discrete variable X in group A is given by x < 12 12 < x < 32 32 < x < 48 48 ≤ x The cumulative frequency function of the same variable in group B is given by x < 32 32 ≤ x < 48 48 < x < 75 75 ≤ x Consider the mixture of the two distributions, i.e., the distribution of the same variable when the two groups are combined into one larger group, oup AB. Assume the weight of group A is 0.48. Enter below the variance of the distribution (of variable X in group) AB. FA(x) = = FB(x) = 0.1. 0.699, 1, 0, 0.151, 0.699,
