2. A manufacturer of chocolate candies uses machines to package candies as they (4 pts) move along a filling line. The company wants the packages to contain 8.1730 ounces of candy. A sample of 50 packages is randomly selected periodically and the packaging process is stopped if there is evidence to show that the mean amount is different from 8.1730 ounces tested at a 95.00% confidence interval/level. In one particular sample of 50 packages, the MEAN.S is equal to 8.1590 ounces, with a STDEV.S of 0.0510 ounce - should the packaging process be halted? What will be the hypothesis in this study? What will be the area of rejection in this study using t Stat critical value? Create the statement of rejection or not-rejection based upon the t Stat value and the t Stat critical value What will be the conclusion of this study?

A manufacturer of chocolate candies uses machines to package candies as they move along a filling line. Although the packages are labeled as 8 ounces, the company wants the pack-ages to contain a mean of 8.17 ounces so that virtually none of the packages contain less than 8 ounces. A sample of 50 packages is selected periodically, and the packaging process is stopped if there is evidence that the mean amount packaged is different from 8.17 ounces. Suppose that in...

4) TURRONITIS S.A. It is a Valencia-based company that produces delicious hazelnuts and chocolate candies. The company decided to sell 200,000 boxes of candy products in Mexico. To this end, the administrator signed an agreement with 5 import companies that involves a profit margin of 15 % over the price charged to retailers. The agreement fixes FOB prices (in Valencia) in Euro. In addition, we know: Freight and insurance Valencia-Veracruz: € 1,202.02 Import duties: 9% over CIF value (Veracruz) Land...

A manufacturer uses two machines to drill holes in pieces of sheet metal used in engine construction. The workers who attach the sheet metal to the engine become inspectors in that they reject sheets so poorly drilled that they cannot be attached. The production manager is interested in knowing whether one machine is produces more defective drillings than the other machine. As an experiment, employee mark the sheets so that the manager can determine which machine was used to drill...

A firm called AstraZeneca uses labor and machines to produce output according to theproduction function ?(?,?)=4?1/2?1/2 where ? is the number of units of labor used and ? is the number of machines. The cost of labor is $40 per unit and the cost of using a machine is $10. (a) On a graph, draw an isocostline for this firm, showing combinations of machines and labor that cost $400 and another isocost line showing combinations that cost $200. What is...
