Consider the data provided below containing cost values for triangular distributions for five WBS elements whose sum comprise the total cost, as well as a correlation matrix for the five WBS elements. Assume Xr=X1+X2+X3+X4+X5 , and use the FRISK method to determine the mean and standard deviation of the total cost, mue r and SDr, and sketch the PDF of Xr.

2. Refer to the triangular cost distribution data provided in problem
   1. Perform a Monte Carlo simulation to develop the total cost distribution for Xr. Dont forget to use the correlation matrix and use 10,000 iterations. Attach your spreadsheet, and a printout of your final cost distribution and S curve.

2. Provide a brief discussion of the differences between the results of problem 2 and your Monte Carlo simulation results.
