Question
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
8.161
ounces, with a sample standard deviation of
0.048
ounce. Complete parts (a) and (b).Click here to view page 1 of the critical values for the t Distribution.
