Directions: Part I (10 points). Calculate the flowing components from the Creatinine Kinase Control Leve" (Lot # CV45 R78 Expiration 10/2012) measured over a 30 day period. To receive full credit show your work as best as possible.

What is the value of +2SD that would be plotted on the Levy-Jennings Chart? What is the value of -2SD that would be plotted on the Levy-Jennings Chart? What is the value of-1SD that would be plotted on the Levy-Jennings Chart? What is the QC Confidence Interval? Calculate the Cocfficient of Variation. Why not? Is the CV acceptable? Why or
