The new commercial controls arrived for the lab's glucose test; one normal control and one abnormal-high control. A lab scientist ran the new controls in duplicate for ten days and obtained the glucose values listed in the chart below. 1. Calculate the mean, standard deviation, and coefficient of variation for the normal control. 2. Calculate the mean, standard deviation, and coefficient of variation for the abnormal control. 3. Determine the 1SD, 2SD, and 3SD ranges for the normal control. 4. Determine the 1SD, 2SD, and 3SD ranges for the abnormal control. 5. Using either the blank Levey-Jennings chart provided or the Westgard QC Plotter tool, fill in the mean and SD ranges, and plot the QC points for both the normal and abnormal control. 6. Are there any Westgard Rule violations?
