Question 1

Correct Answer:

Verified

a.Determine $\bar{P}$ 88/2000 = 0.044 or 4.4%
b.Determine σ_P.
σP = $\sqrt{\frac{(\bar{P})(1-\bar{P})}{n}}$ = $\sqrt{\frac{.044(0956)}{100}}$ = 0.02
c.Determine the 3-sigma UCL and LCL.
UCL = .044 + 3(.02)= 0.105; LCL = .044 - 3(.02)= 0
d.Does the process appear to be in statistical control?
1 point close to UCL; half above and below $\bar{P}$ ; probably in control.Should create a graph to look for patterns.

Question 3

Correct Answer:

Verified

?a.SPC - SPC stands for statistical process control.SPC is a statistical quality control method.SPC monitors quality during production through the use of statistical methods.
In other words,it is a way to monitor the quality being output by a process using statistical methods.SPC allows firms to visually monitor performance,compare the performance to desired levels or standards,and take corrective steps quickly before major errors are made and/or reach the customer.
b.Acceptance Sampling - Acceptance sampling is also a statistical quality control method.Acceptance sampling determines the quality of a finished batch of product based upon statistical methods using a sample of finished batch.
DIFFERENCE: While both SPC and acceptance sampling are statistical quality control methods,SPC monitors quality during production in the hopes of detecting defects early in the process and preventing continued production of defective product.Acceptance sampling,on the other hand,measures quality of finished products.Acceptance sampling is utilized only after processing is complete.In some cases,though,it may be the only statistical quality control method option,especially if the organization is purchasing product rather than producing it.

Lean production systems are sometimes referred to as pull systems because demand from customers activates the production actions of the manufacturing facilities.In order for this demand to be communicated to everyone in the supply chain/manufacturing facility a signal must be passed from downstream processing centers to the upstream processing centers.This system of relaying signals is referred to as a:
