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...

1.Express the confidence interval (168.9,309.7)(168.9,309.7) in the form of ¯x±MEx¯±ME. ¯x±ME 2.A quality control company was hired to study the length of meter sticks produced by a certain company. The team carefully measured the length of many many meter sticks, and the distribution seems to be slightly skewed to the right with a mean of 100.03 cm and a standard deviation of 0.13 cm. a) What is the probability of finding a meter stick with a length of more than...

A quality-control engineer wants to find out whether or not a new machine that fills bottles with liquid has less variability than the machine currently in use. The engineer calibrates each machine to fill bottles with 16 ounces of a liquid. After running each machine for 5 hours, she randomly selects 15 filled bottles from each machine and measures the volume of their contents (in ounces). The resulting data is provided in the table below. Is the variability in the...
