Question

creates airbags. The deployment time of an airbag should be between 21 and 27 milliseconds and their current average is 22 milliseconds with a standard deviation of 0.25 milliseconds. Determine the process capability index if they were to center the mean.

Answer 1

4

Step-by-step explanation:

The computation of the process capability index is shown below:

Data provided in the question according to the question is as follows

USL = 27

LSL = 21

X = (21 +27) ÷ 2 = 24 (take the average)

Standard Deviation: 0.25

`C_p_k = Min {((USL - \bar X)/(3\sigma)) , {((\bar X - LSL)/(3\sigma))`

After placing the above values, the process capability index is 4

hence, the process capability index, if they were to center the mean is 4
