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 8.174 ounces, with a sample standard deviation of 0.057 ounce. Complete parts (a) and (b). Click here to view page 1 of the critical values for the t Distribution. Click here to view page 2 of the critical values for the t Distribution. a. Is there evidence that the population mean amount is different from 8.17 ounces? (Use a 0.10 level of significance.) State the null and alternative hypotheses. Hoi u = 8.17 H₁: 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.) Determine the test statistic. The test statistic is 4962

State the conclusion. Do not reject Ho. There is insufficient evidence to conclude the population mean amount is different from 8.17 ounces. b. Determine the p-value and interpret its meaning. The p-value is (Round to four decimal places as needed.)
