You are the quality control manager in a plant that produces bunjee cords. Your responsibility is to oversee the production of the synthetic material in the cord. Specifically, your responsibility is to ensure that bunjee cords have the correct elastic qualities to avoid personal injury lawsuits. Your efforts are compounded in that you use two procedures for testing bunjee cord elasticity, procedure A and procedure B. Procedure A is generally subject to error, but few are very large. On the other hand, procedure B is very accurate but subject to large one-time errors. Specifically, forecast errors in evaluating the dynamic cord elasticity per pound of load are presented below for a random sample of four cords. Procedure A Forecast error: Calculate the MSE -.01 .01 -.02 .02 a. .0158 b. .00025 C. .015 O d.o You are the quality control manager in a plant that produces bunjee cords.
