PROBLEM C: Use the following to answer questions i - ii:McDaniel Shipyards wants to develop control charts to assess thequality of its steel plate. They take ten sheets of 1" steel plateand compute the number of cosmetic flaws on each roll. Each sheetis 20' by 100'. Based on the following data, develop limits for thecontrol chart, plot the control chart, and determine whether theprocess is in control.
Numbers of
Sheet flaws
1 1
2 1
3 2
4 0
5 1
6 5
7 0
8 2
9 0
10 2
i. Calculate the standard deviation of controlchart.
a. the standard deviation = 1.0832
b. the standard deviation = 1.1832
c. the standard deviation = 1.4
d. the standard deviation = 1.04
ii. Using 3 limits, calculate the LCL and UCL forthese data.
a. UCL = 3.549; LCL = -3.549
b. UCL = 3.549; LCL = 0
c. UCL = 1.4; LCL = -1.4
d. UCL = 4.949; LCL = 0
e. UCL = 1.4; LCL = 0------------------------------
