QUESTION 7 A production filling operation has a historical standard deviation of 6 ounces. When in proper adjustment, the mean filling weight for the production process is 50 ounces. A quality control inspector periodically selects at random 36 containers and uses the sample mean filling weight of 48.6 ounces to see if the process is in proper adjustment or not. Using a standardized test statistic to test the hypothesis at the 5% level of significance, one can reject the null hypothesis and infer that the process is out of proper adjustment. O True O False

A production filling operation has a historical standard deviation of 6 ounces. When in proper adjustment, the mean filling
weight for the production process is 50 ounces. A quality control inspector periodically selects at random 36 containers and
uses the sample mean filling weight of 48.6 ounces to see if the process is in proper adjustment or not. Using a
standardized test statistic to test the hypothesis at the 5% level of significance, one can reject the null hypothesis and infer
that the process is out of proper adjustment.
