The chemistry department at your facility just received a shipment with a new lot of quality control material for electrolytes. You are assigned the task of determining statistics and ranges for potassium. You run the sample three times per day for eight days. The following data points were obtained Day Shift 1 Shift 2 Shift 3 1 4.0 2.3 4.9 2 3.4 3.3 3.1 3 4.6 5.5 2.6 4 3.4 3.5 4.0 5 4.0 2.6 48 6 4.2 3.6 4.8 7 5.6 3.8 3.5 8 8 3.8 3.7 3.6 Use this data to dotermine statistics in the next few questions. The mean of this dataset is (format answer xxx) 1 points Save As QUESTION 2 A standard deviation must be determined for the potassium level one OC range. Using the above data, the standard deviation is (Format answer xxx) 1 points Save A QUESTION 3 Your supervisor has also asked you to determine the coefficient of variation. The CV of the potassium control data is (format answer xx.xx)
After completing your calculations, you should determine the acceptable control rango for this level of potassium QC material. Establish +/- 2 and 3 standard deviation limits as ranges to evaluate OC data. The 25 controllimits are and The 3s control limits are and format all answers xxx)
