A company making tires for bikes is concerned about the exact width of their cyclocross tires. The company has a lower specification limit of 22.9 mm and an upper specification limit of 23.2 mm. The standard deviation is 0.14 mm and the mean is 0.15 mm.

Process capability index = 0.3571

Explanation:

Process Capability Index  or Capability ratio is a measure of the ability of a process to produce output within certain limitations.

It is given by the equation:

Capability Ratio = (USL - LSL) / (6σ)

Here,

= (23.2 - 22.9) / 6x0.14

=(0.3) / 0.84

= 0.3571
