Question Completion Status: QUESTION 4 A quality inspector took five samples, each with six observations of the length of time (in minutes) for glue to dry. The analyst computed the mean of each sample as 12.36, 12.38, 12.18, 12.26, and 11.50. Use this information and alpha risk of 0.02 to obtain control limits for means of future times. It is known from previous experience that the standard deviation of the process is 1.23 minute. STEP 1: Provide controllimits for the mean charti LCL- CL- UCL STEP 2: The inspector continued to periodically sample the process and recorded values for six samples as shown in the following table.
