4.1 The estimated cost to maintain the ANR model was $300,000. Below is the result of a risk model simulation that was obtained using the various inputs into the model to justify maintaining the model. Estimate the following: + Estimate the probability of the estimated cost will be $300,000 The cost of maintenance at a 50% confidence level The cost of maintenance at a 90% confidence level 0.371 1.550 5.0% 93.8% 1.2% 1.4 1.2- 1.0 0.8 - Values x 10^-6 0.6 0.4 0.2- 0.0 -0.50 0.00 1.00 0.50 1.50 2.00 250 Values in Millions ($)
