The known concentration of glucose in a blood sample is 102 mg/dL. During testing of a new at home glucose monitor, the device gives the following determiniations of glucose in the blood sample: 105.0, 100.7, 112.0, 107.2, and 103.7 mg/dL. Calculate the absolute error and relative error for each measurement made by the glucose monitor.
Although I'd appreciate how to for all of them so I know it's right, please explain step-by-step at least one of them so I can figure out the rest.
