Problem 4 (10 pts) An electronics company is testing their batteries. The test reveals whether a battery has voltage in a specified range (pass) or does not (fail). The sample data below shows how many batteries out of each sample failed the test. A sample consists of 50 observations. Determine the control limits for the fraction of defective batteries using three sigma limits. If the process is not in control, eliminate any values outside of the upper control limit and compute revised limits. SAMPLE 1 2 3 4 5 6 6 7 8 4 2 5 2. 4 8 3 2 N Number of failed batteries
