Two types of phone operating system are being tested to determine if there is a difference in the proportions of system failures (crashes). Fifteen out of a random sample of 150 phones with 051 had system failures within the first eight hours of operation. Ten out of another random sample of 150 phones with 052 had system failures within the first eight hours of operation. 052 is believed to be more stable (have fewer crashes) than 051. What is the p-value? (Round your answer to four decimal places.) .1008 x What information and tools are needed to determine the p-value
