A manufacturer of bolts has a quality-control policy that requires it to destroy any bolts that are more than 4 standard deviations from the mean
A manufacturer of bolts has a quality-control policy that requires it to destroy any bolts that are more than 4 standard deviations from the mean. The quality-control engineer knows that the bolts coming off the assembly line have mean length of 15 cm with a standard deviation of 0.05 cm. For what lengths will a bolt be destroyed? Select the correct choice below and fill in the answer box(es) to complete your choice. (Round to one decimal place as neoded.)

O Is the process in control or out of control? Choose the correct answer below. A liquid-dispensing machine has been designed to fill bottles with 10 liter of liquid. The standard deviation of the process is 0.2 liter. A control chart is shown. The chart has horizontal lines drawn at the mean, H. att 20, and at 30. Determine if the process shown is in control or out of control. Explain. Liquid Dispenser Liquid dispensed (in ters)...

Razorback Pharma is in the business of making hydrogen peroxide. The company’s quality control board requires that each bottle of peroxide should contain at least 16 ounces. The production engineer knows that the amount of peroxide in each bottle is normally distributed with a mean of 16.3 ounces and the standard deviation of 0.3 ounces. What is the approximate probability that any given bottle will contain more than the required 16 ounces of peroxide? a. 0.84 b. 0.66 c. 0.16...

9. A large candy manufacturer produces, packages and sells packs of candy targeted to weigh 52 grams. A quality control manager working for the company was concerned that the variation in the actual weights of the targeted 52-gram packs was larger than acceptable That is, he was concerned that some packs weighed significantly less than 52-grams and some weighed significantly more than 52 grams. In an attempt to estimate o, the standard deviation of the weights of all of the...

A golf balls manufacturer requires that the weights of its golf balls have a standard deviation that is less or equal 0.08 ounces. One of the quality control inspectors says that the machines need to be recalibrated because he believes (claims) the standard deviation of the weighs of the golf balls is more than 0.08 ounces. To test the machines, he selects a random sample of 50 golf balls off the assembly line and finds that they have a mean...

2. A manufacturer of coil springs is interested in implementing a quality control system to monitor his production process. As part of this quality system, it is decided to record the number of nonconforming coil springs in each production batch of size 50. During 40 days of production, 40 batches. Here are numerical summaries of the data. 8 mean 9.325 4.485804 Let X be a random variable representing the number of nonconforming coil springs in a production batch of size...
