Using 'break-even' method, which system is preferred? And when does break even occur? 2) Project Life Cycle Year 3 Year 4 Year 1 Year 2 Year 5 $1000 $2000 $5000 $1200 $8000 1 If the decision point occurs at the end of year 2, what is the present value of the life cycle calculated at the decision point assuming 10% discount rate. 3) Task Time (Min) 35 45 40 38 32 Frequency 5 6 7 3 4 7 3 29 47 a) What is the range of the observation? b) What is the Mct? c) What is the standard deviation of the sample data? d) What is the upper limit (using 85% confident level)? e) What percent of the data lies between 35 and 40 minutes? 4) Subsystem A = 0.95, Subsystem B = 0.90, Subsystem C = 0.95, Subsystem D = 0.85, Subsystem E = 0.80.
