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 packages 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 a particular sample of 50 packages, the mean amount dispensed is 8.168 ounces, with a sample standard deviation of 0.052 ounce. Complete parts (a) and (b).

Is there evidence that the population mean amount is different from 8.17 ounces? (Use a 0.05 level of significance.) State the null and alternative hypotheses. Ho:H = 8.17 H:H + 8.17 (Type integers or decimals.) Identify the critical value(s). The critical value(s) is(are) (Round to four decimal places as needed. Use a comma to separate answers as needed.)
