The manufacturer of a certain type of new cell phone battery claims that the average life span of the batteries is charges; that is, the battery can be charged at least times before failing. To investigate the claim, a consumer group will select a random sample of cell phones with the new battery and use the phones through charges of the battery. The proportion of batteries that fail to last through charges will be recorded. The results will be used to construct a percent confidence interval to estimate the proportion of all such batteries that fail to last through charges.
