glucose concentration intended
to cover the range 50 - 200 mg/dL. A prototype for the device has
been completed, with an
output display indicating the estimated concentration level,
denoted
"CI." To calibrate the
device, the true concentration, denoted "Cr", is manipulated
experimentally and the indicated
values are recorded.

B. In another similar device, it is found that there is a bias error that varies over the input range and that differs depending on whether the input is ascending versus descending. It is determined that the best fitting polynomial of the input-output curve (i.e., C₁ vs. CT) is given by Cla= 0.002 CT² + 0.5 CT + 35 mg/dL when the true concentration is ascending, and Cld = -0.002 CT² + 1.5 CT-5 mg/dL when the true concentration is descending. Compute the % hysteresis of the device.
