The C_pk value for the process is typically represented by the lower of the two capability indices when comparing the process capability to both the upper and lower specification limits. In this case, since the upper tolerance limit is 1.029 and the lower tolerance limit is 1.496, the process capability index (Cpk) would be the lower of these two values, which is 1.029.
