Question
A study of
420,048
cell phone users found that
137
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
0.0256%
for those not using cell phones. Complete parts (a) and (b).a. Use the sample data to construct a
interval estimate of the percentage of cell phone users who develop cancer of the brain or nervous system.
90%
confidence enter your response here%<p<enter your response here%
(Round to three decimal places as needed.)
b. Do cell phone users appear to have a rate of cancer of the brain or nervous system that is different from the rate of such cancer among those not using cell phones? Why or why not?
No,
because
0.0256%
is
included in the confidence interval.Yes,
because
0.0256%
is
included in the confidence interval.Yes,
because
0.0256%
