Use either R or Excel for the following. Provide the formulas or code that you are using. Let x1 be a random variable that is N(100, 225). Let x2 be a random variable that is U(50,150) and let x3 be a random variable that is U(500,1500). Set Y = (X1)(X2)/ (X3) a) Use R to create 500 random numbers of each type (X1, X2, X3 and Y).

b) Estimate P(0.1 < Y < 0.25)

c) Estimate E(Y) and the Standard deviation of Y based on the random numbers.

d) Based on the simulation, what is the maximum value of Y

e) Create a histogram for Y.

use R software Let X be a non-negative random variable with μ = E[X] < ∞. For a random sample x1, …, xn from the distribution of X, the Gini ratio is defined by G=12n2μn∑j=1n∑i=1|xi−xj|.G=12n2μ∑j=1n∑i=1n|xi−xj|. The Gini ratio is applied in economics to measure inequality in income distribution (see, e.g., [168]). Note that G can be written in terms of the order statistics x(i) as G=1n2μn∑i=1(2i−n−1)x(i).G=1n2μ∑i=1n(2i−n−1)x(i). If the mean is unknown, let ˆGG^ be the statistic G with μ replaced...
