If the accepted population error rate is 5% for poor quality in a manufacturing plant, how would you determine if an employee in a manufacturing plant is not meeting the standards for quality?

Expert Solution

The accepted population error rate is 5% for poor quality in a manufacturing plant simply tells us that we are given with the margin of error = 0.05. We must know the confidence interval for determining if an employee in a manufacturing plant is not meeting the standards for quality. If the quality rate for the employee is outside the confidence interval, then we can say that an employee in a manufacturing plant is not meeting the standards for quality.

For example, let us consider we are given with the confidence interval for the standard quality rate lies between 12.2 and 14.56 and the margin of error is 0.05. If the quality rate of an employee is 11.48, then it is obvious to say that an employee in a manufacturing plant is not meeting the standards for quality. If the quality rate of an employee is 13.39, then we can say that an employee in a manufacturing plant is meeting the standards for quality.

Therefore, confidence interval of the quality rating will help us in determining if an employee in a manufacturing plant is meeting the standards for quality.

You are the quality assurance person working an assembly line at a TV manufacturing plant. They produce 1000 TV’s a day.

If the inspector were lazy, how would they likely do it as a “convenience” sample? Lastly, if the 1000 TV’s were 4...

PIK Manufacturing rewards its plant managers for their ability to meet budgeted quality cost reductions. The bonus is increased if the productivity goal is met or exceeded. The productivity goal is computed by multiplying the units produced by the prevailing market price and dividing this measure of output by the total cost of the inputs used. Additionally, if the plant as a whole meets the budgeted targets, the production supervisors and workers receive salary and wage increases. Jim Smith, the...
