In a study of 420,082 cell phone? users, 131 subjects developed cancer of the brain or nervous system. Test the claim of a somewhat common belief that such cancers are affected by cell phone use. That? is, test the claim that cell phone users develop cancer of the brain or nervous system at a rate that is different from the rate of? 0.0340% for people who do not use cell phones. Because this issue has such great? importance, use a 0.005 significance level. Identify the null? hypothesis, alternative? hypothesis, test? statistic, P-value, conclusion about the null? hypothesis, and final conclusion that addresses the original claim. Use the? P-value method and the normal distribution as an approximation to the binomial distribution.

What is the test statistic? z = ____ ?(Round to two decimal places as? needed.)

What is the P-value? P-value =____ (Round to four decimal places as? needed)
