The Capability Index (Cpk) is a statistical measure of a process's ability to produce output within specified limits. The formula for Cpk is the minimum of two ratios: (USL - μ) / (3σ) and (μ - LSL) / (3σ), where USL is the upper specification limit, LSL is the lower specification limit, μ is the mean, and σ is the standard deviation. For this process: Cpk = min[(550 - 545) / (3*0.75), (545 - 540) / (3*0.75)] = min[5 / 2.25, 5 / 2.25] = 2.22.
