A 23 factorial experiment is run using the following levels.
For X1: 10 and 20
For X2: 5 and 10
For X3: 20 and 30
The low level for each factor is represented by 1, and the high level is represented by 2. The
following table shows the results obtained at random for the eight experimental conditions of the
design:2 = ?
