In a study of 420 comma 113 cell phone users, 139 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 greatimportance, use a 0.001 significance level. Identify the null hypothesis, alternative hypothesis, test statistic, a. What is the test statistic? z equals (Round to two decimal places as needed.) b. What is the P-value?
