Excellent. (Via Marginal Revolution.)

Which of the following statements about *p*-values is correct?

**1.**A

*p*-value of 5% implies that the probability of the null hypothesis being true is (no more than) 5%.

**2.**A

*p*-value of 0.005 implies much more "statistically significant" results than does a

*p*-value of 0.05.

**3.**The

*p-*value is the likelihood that the findings are due to chance.

**4.**A

*p*-value of 1% means that there is a 99% chance that the data were sampled from a population that's consistent with the null hypothesis.

**5.**None of the above.
