8: A philosophy professor wants to find out whether the mean age of the men in his large lecture class is equal to the mean age of the women in his classes. After collecting data from a random sample of his students, the professor tested the hypothesis Ho: μ_w-μ_m=0, against the alternative Ha : μ_w-μ_m≠0. The P-value for the test was 0.003. Which is true?

A) There is a 0.3% chance that the mean ages for the men and women are equal.

B) There is a 0.3% chance that the mean ages for the men and women are different.

C) It is very unlikely that the professor would see results like these if the mean age of men was equal to the mean age of women.

D) There is a 0.3% chance that another sample will give these same results.

E) There is a 99.7% chance that another sample will give these same results.
