Use a Box Behnken design to estimate the parameters in aquadratic expression for hydrocarbon concentration.If z is the distance below grade and x and y are rectangularco-ordinates relative to the centre of the 10 m x 10 m square,x = -5 implies x coded = -1 and x = 5 implies x coded = 1y = -5 implies y coded = -1 and y = 5 implies y coded = 1z = 5 implies z coded =1, z = 2.5 implies z coded = -1 andz = 3.75 implies z coded = 0Samples were taken and the following were the results:CEI Inc.
