7 A production line operates with a mean filling weight of 1

7. A production line operates with a mean filling weight of 16 ounces per container. Overfilling or underfilling presents a serious problem and when detected requires the Operator to shut the production line to adjust the filling mechanism. From past data, a Population standard deviation o =. 8 ounces is assumed. A quality control inspector selects a sample of loo items every hour and at that time makes the decision of whether to shut do the line for readjustment. The level of significance is alpha=0.05 a. State the hypothesis test for the quality control application. b. If a sample mean of x bar = 16.2 ounces were found, what is the p?value? What action would you recommend? c. If a sample mean of x bar = 15.9 ounces were found, what is the p-value? What action would you recommend?
