Acceptance sampling is an important quality control technique, where a batch of data is tested to determine if the proportion of units having a particular attribute exceeds a given percentage. Suppose that 8% of produced items are known to be nonconforming. Every week a batch of items is evaluated and the production machines are adjusted if the proportion of nonconforming items exceeds 10%. [You may find it useful to reference the z table.]

a. What is the probability that the production machines will be adjusted if the batch consists of 65 items? (Round “z” value to 2 decimal places, and final answer to 4 decimal places.)

b. What is the probability that the production machines will be adjusted if the batch consists of 77 items? (Round “z” value to 2 decimal places, and final answer to 4 decimal places.)

The quality-control inspector of a production plant will reject a batch of syringes if two or more defective syringes are found in a random sample of nine syringes taken from the batch. Suppose the batch contains 1% defective syringes. (a) Make a histogram showing the probabilities of r = 0, 1, 2, 3, , 8 and 9 defective syringes in a random sample of nine syringes. (b) Find μ. What is the expected number of defective syringes the inspector will...
