Chapter 11, Problem 11.2.4CP

Process A produces 1,000 defect-free parts per hour. After every 2 hours, the equipment must be adjusted. This adjustment takes 15 minutes. The machine operator, who also makes the adjustment, is paid $25 per hour (this includes fringe benefits). Process B produces 750 defect-free parts per hour. The equipment needs to be adjusted by the operator every 4 hours. This adjustment requires 10 minutes of the operator’s time (paid at $15 per hour which includes fringe benefits). Both processes are operated 8 hours a day. If each defect-free part can be sold for $0.10, which process should be selected? Be sure to list your key assumptions.

You work for the U.S. Food and Drug Administration. You have gotten word that a drug manufacturing is not accurately reporting the contents of their liquid cold medication. Under Federal Regulations, "Variations from stated quantity of contents shall not be unreasonably large" (see section q of the regulation by clicking here).The company that produces the cold medication is claiming that each bottle contains 355 milliliters of cold medication, which is about 12 fluid ounces. In order to determine if they are accurate in their reporting, you decide to randomly select 20 different bottles of cold medication and measure the amount of cold medication in each bottle (in milliliters). The results of each sample are shown below. Bottle Number 1 2 3 4 5 6 7 8 9 10 Milliliters 342 353 357 353 351 348 352 359 354 358   Bottle Number 11 12 13 14 15 16 17 18 19 20 Milliliters 342 351 341 353 352 344 348 355 349 353 a) Use the data shown above to construct a 96% confidence interval…
