If U1 and U2 are i.i.d. Unif(0,1) with U1 = 0.25 and U2 = 0.25, use Box–Muller to generate two i.i.d. Nor(0,1) realizations. This should generate two different Z1 and Z2 values.
1) In this exercise, we are given the distribution of Sn=U1+U2+…+Un, where Ui are i.i.d. Uniform(a=0,b=1) random variables. a) Find the p.d.f. of S3=U1+U2+U3 and sketch its graph. b) Find the p.d.f. of S4=U1+U2+U3+U4 and sketch its graph c) Neither S3 or S4 are distributions with a name, but if you sketch their p.d.f.s, they should resemble a previous distribution. Which one?
