Answer:

Process capability index (cp) for the chip filling process is 0.56

Explanation:

Process capability index (cp) = (Upper Specification Limit - Mean) / (3 * standard deviation) = (Mean - Lower Specification) / (3 * standard deviation)

Process capability index (cp) = (10.5 - 10) / (3*0.3)

Process capability index (cp) = 5/9

Process capability index (cp) = 0.56
