When calibrating a temperature sensor using a precise reference
instrument, the following relationship is obtained between
reference temperature T (degrees C) and sensor value Y (mV).
  T (C) Y (mV)

Estimate the parameters b0, b1, b2 for the square regression curve y = b0 + b1 T + b 2 T 2
The equation:

The parameters are given by the system of equations:

Data:

We will solve the above system of equations using cramers rule.




Therefore, using cramers rule,



Therefore the equation:
