A study of 420,095 cell phone users resulted in 135 who developed cancer of the brain or nervous system. When comparing this sa
mple group to another group of people who did not use cell phones, it was found that there is a probability of 0.512 of getting such sample results by chance. What do you conclude?
A probability of 0.512 that the results obtained in the controlled sample could be obtained by chance, means that it is more likely than not ( P>0.50) to get this results by chance. What this means is that the results of the original study linking brain cancer development to cell phone use are inconclusive.
