(a) You are the project manager for a new high-rise office building. You are working on estimating the exterior landscaping for the new development. The landscaping requires the use of a special landscape stone. Based on recent experience the most likely price for the material is $120.00/ton. However, the price for this stone is volatile, and the price fluctuates over time based on market conditions and material availability. The most optimistic price estimate is $60.00/ton, and the most pessimistic estimate is $160.00/ton. (Note there are 3 data points in for this estimate.)
What is the expected price of the material?
