Question

Question Help In a study of 420,099 cell phone users, 137 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 0.001 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 c. Họ p= 0.00034 D. Ho p = 0.00034 HD 0.00034 H, p<0.00034 O E. Ho p>0.00034 Ho D#000034 Hy p=0.00034 Hp +0.00034 What is the test statistic? (Round to two decimal places as needed.)

Answer 1

solution: - 137 0.00034 t 7 = 3\ 420099 pl-b (0.00034) (1-0.00034) 4 200g - O.49 * p-value Plze z (-0.49 08 or Z) 0.49) please check 0.6242 decimal needed since, P-valul sa Failed to reject no
