Consider a production process that produces tires.A quality engineer has taken 15 samples,each containing 200 tires.The total number of defective tires over the 15 samples is 340.The centerline for the control chart is
A)0.08
B)0.11
C)0.16
D)0.21

Question

Quizplus · Accepted Answer

The centerline for the control chart is calculated as follows:
Centerline = (Total number of defects) / (Total number of samples x Sample size)
Centerline = 340 / (15 x 200)
Centerline = 0.1133
Therefore, the closest option to the calculated centerline is B) 0.11.
