C-Spec, Inc., is attempting to determine whether an existing machine is capable of milling an engine part that has a key specification of 3 0.003 inches. After a trial run on this machine, C-Spec has determined that the machine has a sample mean of 3.001 inches with a standard deviation of 0.002 inch.

Calculate the C_pk for this machine. (Round your answer to 3 decimal places.)
