AP* Statistics Quiz C - Chapter 11 Name DoMinkim As a 4-H project, Billy is raising chickens. He feeds and waters them every day, and collects the eggs every other day, selling them to people in the neighborhood. He has found that each hen's nest will contain from 0 to 2 eggs. Based on past experience he estimates that there will be no eggs in $ 10 \% $ of the nests, one egg in $ 30 \% $ of the nests, and 2 eggs in the other $ 60 \% $. Conduct a simulation to estimate how many nests Billy will have to visit to collect a dozen eggs. 1. Describe how you will use a random number table to conduct this simulation. 2. Show three trials by clearly labeling the random number table given below. Specify the outcome for each trial. $ 57528 \quad 78305 \quad 63508 \quad 29418 $ $ 90676 \quad 31993 \quad 5463617877 $ $ 31574 \quad 28042 \quad 7262184818 $ 3.

In a balanced three-phase system, the source has an abc sequence, is Y-connected, and $V_{an} = 250\angle -45^\circ$ V. The source feeds two loads, both of which are Y-connected. The impedance of load 1 is $20 + j30 \Omega/\phi$. The complex power for the a-phase of load 2 is $500\angle 30^\circ$ VA Find the total complex power supplied by the source. Express your answer in volt-amperes to three significant figures. Enter your answer using angle notation. Express argument in degrees. $S_T = $ VA

5. (i). What are the key components of a balance sheet? Define each component. (ii). What is the purpose of: (a) engineering economics analysis and (b) financial analysis? (iii). State your understanding of the following engineering economic analysis techniques: (a) net present value (NPV), (b) rate of return on investment (ROI) and (c) internal rate of return (IRR). 6. (i). Briefly explain the following quality management techniques: (a) Kaizen, (b) failure mode and effect analysis (FMEA and (c) quality function deployment (QFD). (ii) What is the purpose of root cause analysis used in process management? State the root case analysis techniques used to dig deeply into a problem. (iii) What are the typical project management software programs used in industry? 7. Many Canadian companies have adopted a form of workforce management that they believe will enable them to compete better in the world market. They keep a "core of management and valued workers" whom they favour with good benefits and permanent jobs. They take on and shed other workers as business spurs and slumps." These jobs pay less and have few if any benefits. Answer the following questions: (i) What is likely to be the impact of this trend on employee motivation? Will temporary workers be as motivated as permanent employees, especially if they continue to look for a "decent" job? (ii) How will this, in turn, affect production and service to customers? Given the growing importance of teamwork and cooperation, is quality production likely to suffer? (iii) What are the long-term impact on the competitiveness of companies? (iv) How can companies develop employees' long-term loyalty in such circumstances?
