What is the variance of the distribution of variable X in group AB The cumulative frequency function of a discrete variable X in group A is given byx < 1212 ≤ x < 3232 < x < 4848 ≤ xThe cumulative frequency function of the same variable in group B is given byFA (X) ==0,0.1,0.699,1,0,x < 320.151,32 < x < 480.699,48 ≤ x < 751,75 ≤ xConsider the mixture of the two distributions, i.e., the distribution of the same variable when the two groups arecombined into one larger group, group AB.Assume the weight of group A is 0.48.Enter below the variance of the distribution (of variable X in group) AB.FB (X)
