Question
The life expectancy of a male during the course of the past 100 years is approximately 27,747 days. Use the table to the right to conduct a test using a = 0.05 to determine whether the evidence suggests that chief justices live longer than the general population of males. Suggest a reason why the conclusion drawn may be flawed. State the appropriate null and alternative hypotheses. A. Ho: μ = 27,747 versus H₁: µ‡27,747 C. Ho: μ = 30,581 versus H₁: µ# 30,581 E. Ho: μ = 30,581 versus H₁: μ< 30,581 Use the P-value approach at the x = 0.05 level of significance to test the hypotheses. P-value = (Round to three decimal places as needed.) B. Ho: μ=27,747 versus H₁: µ<27,747 D. Ho: μ = 30,581 versus H₁: μ>30,581 OF.

Choose the correct answer below. A. Reject the null hypothesis. There is sufficient evidence to conclude that the mean life span of males is longer than 27,747 days. Thus, there is sufficient evidence to indicate that chief justices live longer than the general population of males. B. Reject the null hypothesis. There is not sufficient evidence to conclude that the mean life span of males is longer than 27,747 days. Thus, there is not sufficient evidence to indicate that chief justices live longer than the general population of males. C. Do not reject the null hypothesis. There is not sufficient evidence to conclude that the mean life span of males is longer than 27,747 days. Thus, there is not sufficient evidence to indicate that chief justices live longer than the general population of males.

Choose the correct answer below. A. The sample is not obtained using simple random sampling or from a randomized experiment. B. The sample consists of outliers. C. The sample size is very large and the data are normally distributed. D. The sampled values are not independent of each other.
