Question

In a study of 420 comma 043 cell phone​ users, 182 subjects developed brain cancer. Test the claim that cell phone users develop brain cancer 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. Use this information to answer the following questions. a. Which of the following is the hypothesis test to be​ conducted? A. Upper H 0 : p equals 0.00034 Upper H 1 : p less than 0.00034 B. Upper H 0 : p equals 0.00034 Upper H 1 : p greater than 0.00034 C. Upper H 0 : p less than 0.00034 Upper H 1 : p equals 0.00034 D. Upper H 0 : p not equals 0.00034 Upper H 1 : p equals 0.00034 E. Upper H 0 : p greater than 0.00034 Upper H 1 : p equals 0.00034 F. Upper H 0 : p equals 0.00034 Upper H 1 : p not equals 0.00034 b. What is the test​ statistic? zequals nothing ​(Round to two decimal places as​ needed.) c. What is the​ P-value? ​P-valueequals nothing ​(Round to four decimal places as​ needed.) d. What is the​ conclusion? A. There is not sufficient evidence to support the claim that cell phone users develop brain cancer at a rate that is different from the rate of​ 0.0340% for people who do not use cell phones. B. There is sufficient evidence to support the claim that cell phone users develop brain cancer at a rate that is different from the rate of​ 0.0340% for people who do not use cell phones. e. Should cell phone users be concerned about brain​ cancer? A. No comma the study does not suggest that a cell phone user is at a higher risk for brain cancer than a non cell phone user. B. Yes comma the study suggests that a cell phone user is at a higher risk for brain cancer than a non cell phone user. Click to select your answer(s).
