A p-chart has been developed for a particular item. In the past, 3% of such items have been found to be defective. If a sample of 100 is taken, and 9 of these are found to be defective, should the process be considered out of control? Explain© BrainMass Inc. brainmass.com June 4, 2020, 12:15 am ad1c9bdddf
p = 0.03, n = 100
Standard error, SE = sqrt[p(1 - p)/n] = sqrt[0.03(1 - 0.03)/100] = ...
The expert examines if the process is out of control using a p-chart. A complete, neat and step-by-step solution is provided.
