Question
In a study of 420, 087 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 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 the original claim. Use the P-value method and the normal distribution as an approximation to the binomial distribution. Which of the following is the hypothesis test to be conducted? A. H_0: p notequalto 0.00034 H_1: p = 0.00034 B. H_0: p 0.00034 D. H_0: p = 0.00034 H_1: p notequalto 0.00034Explanation / Answer
FOR THE GIVEN TESTING PROBLEM THE NULL AND ALTERNATIVE HYPOTHESIS ARE IN THE OPTION D.
H0 : P=0.00034 H1 : P# 0.00034
