Question 7 (1 point) As a quality control inspector of a packaging company, you want to control the weight of a packaging process. At the end of each day during the last three days, you have randomly selected a sample of four packages and weighed each: Question 9 ( 3 points) Refer to the information in Q7. Suppose the process standard deviation is not known. Based on the above data (Monday-Wednesday), construct the 3- control limits for the mean chart. UCL=608.63,LCL=581.37UCL=630.24,LCL=580.12UCL=595,LCL=570.2UCL=630.12,LCL=560.23 Question 10 (3 points) Refer to the information in Q7. Suppose that from past experience you know that whenever this process is under control, package weight is normally distributed with a standard deviation of 22.32 ounces. What are the 3 control limits for your mean chart?
