We are planning a project and analyzing the following information: There is 15 % probability that the cost of materials will be $9,000 less than expected There is 20 % probability of a delay in the receipt of some parts, with a cost to the project of $9,000 There is a 15% probability of a design defect, causing $ 7,000 of rework There is a 45 % probability that the construction of some activities may be simpler than expected, saving $1,500 There is a 20% probability that two parts will not fit together when installed, costing an extra $1,000 Based on this information, what are the cost contingency reserves that we should use
