Of what is p the probability?
A. p is the probability of observing a test statistic at least as big as the one we have if there were no effect in the population (i.e., the null hypothesis were true). B. p is the probability that the results are due to chance, the probability that the null hypothesis (H0) is true. C. p is the probability that the results are not due to chance, the probability that the null hypothesis (H0) is false. D. p is the probability that the results would be replicated if the experiment was conducted a second time.
