1. Using the glucose values below, calculate the following: 1 pt each 100 mg/dL 100 mg/dL 99 mg/dL 100 mg/dL 102 mg/dL 94 mg/dL 93 mg/dL 97 mg/dL 95 mg/dL a. Mean b. Median c. Mode d. Range of values over 9 days 2. Calculate the QC 2 SD limits for each value: 1 pt each a. Urea Nitrogen positive control mean of 14 mg/dL with a SD of 3 mg/dL. b. Control Level II mean of 350 U/L with SD 1 = 25 U/L 3. Your lab manager asks you to create the control range for the new lot of hematology control level 1. The following 20 hemoglobin values are gathered to determine the control limits. All values are in g/dL. 3 pts Hemoglobin value in g/dL 4.2 4.7 4.2 4.7 4.6 4.7 4.3 4.7 4.6 4.4 4.9 4.0 4.0 5.0 4.4 4.5 4.8 4.4 a. Calculate the mean b. Calculate 1SD c. Calculate the 95% confidence interval 4. You perform a normal serum glucose control and obtain a value of 78.4 mg/dL. The mean for this control is 74.8 mg/dL and 1 SD has been calculated as 1.2. Is the value of 76.4 mg/dL within the 95% confidence
