A manufacturer of chocolate candies uses machines to package candies as they move along a filling line. Although the packages are labeled 8 ounces, the company wants the packages to contain 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 a particular sample of 50 packages the mean amount dispenses is 8.159 ounces, with a sample standard deviation of 0.051 ounces.Use the critical value approach to determine if there is evidence that the population mean amount is different from 8.17ounces? (use a 0.05 level of significance)Determine the p-value for this test. Is the p-value consistent with the result in part a?

Question

A manufacturer of chocolate candies uses machines to package candies as they move along a filling line. Although the packages are labeled 8 ounces, the company wants the packages to contain 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 a particular sample of 50 packages the mean amount dispenses is 8.159 ounces, with a sample standard deviation of 0.051 ounces.
Use the critical value approach to determine if there is evidence that the population mean amount is different from 8.17ounces? (use a 0.05 level of significance)
Determine the p-value for this test. Is the p-value consistent with the result in part a?
