Question

In a study of 420,096 cell phone users, 113 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.

In a study of 420 comma 052 cell phone users, 136 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,...

In a study of 420 comma 136 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,...

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...

In a study of 420,019 cell phone users, 172 of the subjects
developed brain cancer. Test the claim that cell phone users
developed brain cancer at a greater rate than that for non-cell
phone users (the rate of brain cancer for non-cell phone users is
0.0340%). Since this is a critical issue, use a 0.005 significance
level. Explain why the significance level should be so low in terms
of a Type I error.

A study of 420,095 cell phone users found that 134 of them
developed cancer of the brain or nervous system. Prior to this
study of cell phone use, the rate of such cancer was found to be
0.0328% for those not using cell phones. a. Use the sample data to
construct a 90% confidence interval estimate of the percentage of
cell phone users who develop cancer of the brain or nervous system.
__% < p < __%

A study of 420,059 cell phone users found that 135 of them
developed cancer of the brain or nervous system. Prior to this
study of cell phone use, the rate of such cancer was found to be
0.0314% for those not using cell phones. Complete parts (a) and
(b).
a)Use the sample data to construct a
95% confidence interval estimate of the percentage of cell
phone users who develop cancer of the brain or nervous system.
b) do cell phone...

A
