16. b. Identify the test statistic c. The P-value for this hypothesis test is In a study of 420,093 cell phone users, 100 subjects developed cancer of the brain or nervous system. Test the claim of a somewhatcommon belief that such cancers are affected by cell phone use. That is, test the claim that cell phone users develop cancer of the brain ornervous 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 suchgreat importance, use a 0.001 significance level. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion aboutthe null hypothesis, and final conclusion that addresses the original claim. Use the P-value method and the normal distribution as anapproximation to the binomial distribution.

Given sample size and sample proportion we use one same z proportion .

A fast-food restaurant claims that a small order of french fries contains 120 calories. A nutritionist is concerned that the true average calorie count is higher than that. The nutritionist randomly selects 35 small orders of french fries and determines their calories. The resulting sample mean is 155.6 calories, and the pp-value for the hypothesis test is 0.00093. Which of the following is a correct interpretation of the p-value? A)If the population mean is 120 calories, the p -value of 0.00093 is the probability of observing a sample mean of 155.6 calories or more. B) If the population mean is 120 calories, the p -value of 0.00093 is the probability of observing a sample mean of 155.6 calories or less. C)If the population mean is 120 calories, the p -value of 0.00093 is the probability of observing a sample mean of 155.6 calories or more, or a sample mean of 84.4 calories or less. .D)If the population mean is 155.6 calories, the p -value of 0.00093…
