+ The advertised claim for batteries for cell phones is set at 48 operating hours with proper charging procedures. A study of 5000 batteries is carried out and 15 stop operat- ing prior to 48 hours. Do these experimental results support the claim that less than 0.2 percent of the company's batter- ies will fail during the advertised time period, with proper charging procedures? Use a hypothesis-testing procedure with a = 0.01.
