Problem Assignment (Project Budgeting) Total points: 20 #1) A Submarine manufacturer is interested in continuing business of building mini submarines bidding for the government to build mini-submarines. The company has built the first mini submarine. The data for the first mini-submarine is as follows: Labor hours 6000 Material cost = $200000 Labor cost $50 per hour The company expects a Learning Rate of 80% in building these mini-submarines Compute total cost of producing the five mini-submarines. (10 points) #2) Month Estimate Actual 1050 1100 1200 1150 950 1000 a) What is the Mean Bias? (3 points) b) What is the Mean Absolute Ratio (MAR)?
