An inspector of a production facility, which produces digital calculators, has collected 10 samples each contained 100 calculators. After the inspection, he found that 15 calculators were defective. Find the UCL and the LCL, by using 2-sigma (z=2). Hint: Sample size is known (n=100)and , the inspection has two possible outcomes (i.e., undefective and defective). In other words, average percentage error can be calculated. UCL=0.039, LCL= 0 UCL = -0.009, LCL = 0.039 UCL=0, LCL=0.039 Cannot be calculated UCL = 0.039, LCL = -0.009

Question

An inspector of a production facility, which produces digital calculators, has collected 10 samples each contained 100 calculators. After the inspection, he found that 15 calculators were defective. Find the UCL and the LCL, by using 2-sigma (z=2). Hint: Sample size is known (n=100)and , the inspection has two possible outcomes (i.e., undefective and defective). In other words, average percentage error can be calculated.

UCL=0.039, LCL= 0
UCL = -0.009, LCL = 0.039
UCL=0, LCL=0.039
Cannot be calculated
UCL = 0.039, LCL = -0.009
