Consider 24 PRNS,U 1,U2,...,U4, and suppose that the average of those observationssU= 24-1 U/24-0.7.Use these PRNs to generate a single approximately Nor(0,1) random variate via our "desert island" technique Consider 24 PRNS,U1, U2,...,U24, and suppose that the average of those observations isU= {i=124Ui/24-0.7.Use these PRNS to generate a single approximately Nor(0,1) random variate via our "desert island technique.
