Answer: attached below is the missing p chart
a) 0.07133
b) 2
c) 0.098
d) 0.045
Step-by-step explanation:
sample size = 150 castings
number of periods = 10
<u>a) Determine the center Line of the control chart </u>
( 0.06 + 0.0933 + 0.06 + 0.06 + 0.0867 + 0.0533 + 0.08 + 0.067 + 0.08 + 0.073) / 10
mean = 0.07133
standard deviation = 0.01335
<u>b) Determine the value of Z to be used </u>
Given that we are using 2sigma limits .
the value of Z to be used = 2
<u>c) Upper limit control</u>
= mean value + z-value * std
= 0.0713 + 2*0.01335 = 0.098
<u>d) Lower Control Limit </u>
= mean value - z-value * std
= 0.0713 - 2*0.01335 = 0.045
