It was announced that a cell phone battery with proper charging procedures can withstand 48 hours of operation. A study was conducted with 5,000 batteries and 15 of them stopped operating within 48 hours. will these experimental studies support the assertion that less than 0.2% of the company's batteries will fail during the published time with proper charging procedures? Use a hypothesis testing procedure with α = 0.01
