Suppose that the following fraction defective has been found in successive samples of size 100 (read down):

Question:

(a) Using all the data, compute trial control limits for a fraction- defective control chart, construct the chart, and plot the data.

0.09 0.03 0.12 0.05 0.10 0.14 0.13 0.13 0.06 0.08 0.10 0.05 0.14 0.14 0.14 0.09 0.07 0.11 0.10 0.06 0.09 0.15 0.09 0.13

(b) Determine whether the process is in statistical control. If not, assume that assignable causes can be found and out-of- control points eliminated. Revise the control limits.
