Web3 I am trying to generate N (0,1) using uniform (0,1) for a simulation but can't get the code to run. Firstly, my x is found by making X the subject for the CDF of normal followed by getting out the histogram. This is followed by imposing a … WebNotice that the standard normal table only gives probabilitiesP(Z ≤ z)forpositive values ofz. To findP(Z ≤−z) for negative values−z, we use the symmetry of the normaldistribution. …
