The initial cost is $2.1 million, and the expected annual costs is $510,000. The range of accuracy for the initial cost is-20% to +20% and 25% to +25% for the annual cost. % . a) Calculate the PW of the Base case based on the above data b) Calculate the PW for the range of -2096 to +2096 for initial cost c) Calculate the PW for the range of -2596 to +2596 for annual cost d) Prepare a tabular distribution by using PW as FoM e) Rank order the input variables for their impact of the PW f) Prepare a sensitivity graph comparing the percentage of deviation frorm [1 point] [0.5 point+0.5 point] [0.5 point+0.5 point] [1 point +1 point] [0.5 point+0.5 point] the base case to the PW.
