The equipment installation group at Globus Enterprises is about to make a cost estimate to determine how much it will cost to install a back-up generator at a government laboratory facility. Over the years, this group has carried out more than 100 such installations and has developed a database reflecting past experience. Data on the distribution of cost for design work, building effort, and testing effort is provided in Table 1.

	Cheapest ($/%)	Usual ($/%)	Expensive ($/%)
Design	9,000/30	10,000/40	12,000/30
Build	60,000/20	70,000/60	80,000/20
Test	18,000/20	20,000/50	24,000/30
Table 1. Historical Data on Cost Distributions The data in the table picture the cost of an effort and the percentage of times this cost is achieved. For example, 30% of the time, Design cost $9,000; 40% of the time it cost $10,000; 30% of the time it cost $12,000.

Conduct a Monte Carlo simulation to create a distribution portraying total estimated project costs. Employ ten iterations in your computation. Display the distribution graphically.
