In a study of 420,052 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, and P-value. Use the​ P-value method and the normal distribution as an approximation to the binomial distribution.
