A consolidation test was done on a sample from the middle of a $20$ ft normally consolidated clay layer. The laboratory test indicated a $c_c=0\mathrm{.}25,c_r=0\mathrm{.}05$ and a ${}_p^{\text{'}}=1,200psf.$ The unit weight of the clay layer is $120$ psf and the water table is at the ground surface level.

Calculate the OCR and determine whether the clay is really an NCC or an OCC
