In a study of

420 comma 116

cell phone users,

128

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?

Upper H 0 : p equals 0.00034

Upper H 1 : p less than 0.00034

Upper H 0 : p greater than 0.00034

Upper H 1 : p equals 0.00034

Upper H 0 : p less than 0.00034

Upper H 1 : p equals 0.00034

Upper H 0 : p equals 0.00034

Upper H 1 : p not equals 0.00034

Upper H 0 : p not equals 0.00034

Upper H 1 : p equals 0.00034

Upper H 0 : p equals 0.00034

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
