question 85

Multiple Choice

Historically, the average proportion of defective bars has been 0.015. Samples will be of 100 bars each. Construct a p-chart using $$z = 3$$ . Suppose a sample had 0.044 defectives. What would be the best action to take in this scenario?

• A) Nothing; it appears to be random variation.
• B) Look for assignable causes.
• C) Change z to 2 and take another sample.
• D) Change z to 4 and continue sampling.
