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 class. After collecting data from a random sample of his students, the professor tested the hypothesis H0: μM - μW = 0 against the alternative HA: μM - μW ≠0. The P-value for the test was 0.003. Which is true?

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

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

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

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

▸ 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.
