Question

n a study of

420,112 cell phone​ users, 110 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 addresses 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.

Upper H 0 : p greater than 0.00034H0: p>0.00034

Upper H 1 : p equals 0.00034H1: p=0.00034

B.

Upper H 0 : p less than 0.00034H0: p<0.00034

Upper H 1 : p equals 0.00034H1: p=0.00034

C.

Upper H 0 : p equals 0.00034H0: p=0.00034

Upper H 1 : p greater than 0.00034H1: p>0.00034

D.

Upper H 0 : p equals 0.00034H0: p=0.00034

Upper H 1 : p not equals 0.00034H1: p≠0.00034

E.

Upper H 0 : p equals 0.00034H0: p=0.00034

Upper H 1 : p less than 0.00034H1: p<0.00034

F.

Upper H 0 : p not equals 0.00034H0: p≠0.00034

Upper H 1 : p equals 0.00034H1: p=0.00034

What is the test​ statistic?

zequals=nothing

​(Round to two decimal places as​ needed.)

What is the​ P-value?

​P-valueequals=nothing

​(Round to four decimal places as​ needed.)

What is the conclusion on the null​ hypothesis?

A.

Fail to rejectFail to reject

the null hypothesis because the​ P-value is

less than or equal toless than or equal to

the significance​ level,

alphaα.

B.

RejectReject

the null hypothesis because the​ P-value is

greater thangreater than

the significance​ level,

alphaα.

C.

Fail to rejectFail to reject

the null hypothesis because the​ P-value is

greater thangreater than

the significance​ level,

alphaα.

D.

RejectReject

the null hypothesis because the​ P-value is

less than or equal toless than or equal to

the significance​ level,

alphaα.

What is the final​ conclusion?

A.There

is notis not

sufficient evidence to warrant rejection of 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%.

B.There

isis

sufficient evidence to warrant rejection of 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%.

C.There

is notis not

sufficient evidence to support 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%.

D.There

isis

sufficient evidence to support 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%.
