An electronic recycler sets refurbished laptop prices based on the number of defects (blemishes) in a batch of 9 laptops. The number of defects in each of 20 batches (samples) of a new shipment are shown below: Number of defects in each sample Sample Defects Sample Defects Sample Defects 1 9 8 1O 15 8 2 6 9 1O 16 8 3 8 10 10 17 10 4 8 1 1 21 18 9 5 9 12 1 1 19 10 6 6 13 8 2O 11 7 7 14 6 Download CSV a} Determine the centerline and the control limits for the c-chart accurate to at least 2 decimal places. Do not r'ound intermediate results. 1. Centreline = C] b) Is the number of defects out of control? 0 Yes. There is at least one point beyond the control limits. 0 No. There is no point beyond the control limits. 0 Yes. There is no point beyond the control limits. 0 No. There is at least one point beyond the control limits. The UCL for an R-chart is 47.9043 for samples of size 12 each taken hourly for 23 hours. What is the mean of the sample ranges? Table of Control Chart Constants Round answer to 1 decimal place. H3 From samples of size n = 5 taken daily for 13 days from a production lot, the mean of the sample ranges, R = 12, and the lower control limit for the i-chart is 114.276. What is the mean of the sample means? Table of Control Chart Constants Round answer to 1 decimal place. C] A manager took samples of size n : 6 hourly from a process for 15 hours and determined the lower and upper control limits for the corresponding Eachart as below: LCL = 81.519 UCL = 88.281 Table of Control Chart Constants Table of Control Chart Constants Sasritlzle A2 D3 D4 2 1.880 0 3.267 3 1.023 0 2.575 4 0.729 0 2.282 5 0.577 0 2.114 6 0.483 0 2.004 7 0.419 0.076 1.924 8 0.373 0.136 1.864 9 0.337 0.184 1.816 10 0.308 0.223 1.777 1 1 0.285 0.256 1.744 12 0.266 0.283 1.717 13 0.249 0.307 1.693 14 0.235 0.328 1.672 15 0.223 0.347 1.653 16 0.212 0.363 1.637 17 0.203 0.378 1.622 18 0.194 0.391 1.609 19 0.187 0.404 1.596 20 0.180 0.415 1.585 21 0.173 0.425 1.575 22 0.167 0.435 1.565 23 0.162 0.443 1.557 24 0.157 0.452 1.548 25 0.153 0.459 1.541 Calculate the following mean values accurate to 1 decimal place: The control limits for a c-chart was reported as the following interval: C + 10.8167 Determine the centreline.
