You're working with a company that produces smartphones and have been tasked to test 6 different lithium-ion batteries from a new vendor. (the test will be an accelerated life simulation which is common in testing) Ideally, the batteries should last 2,000 operating hours before needing replacement. One battery failed at 160 hours, one battery failed at 220 hours and one battery failed at 275 hours. Three batteries successfully completed the simulated 2,000 hours of operations. Based on this data, did the vendor pass the 2,000 hour test? yes no
