Let x¯1 represent the mean of a random sample of size n1, selected from the population
x 2 3 7
F(x) 1/3 1/3 1/3
and x¯2 represent the mean of a random sample of size n2 from the population
x 1 3
F(x) 2/3 1/3
if independent samples of size n1 = 125 and n2 =100 are drawn with replacement, what is the probability that the difference between x¯1 and x¯2 will be greater than 1.84 but less than 2.627
