Question 4
0..5 pts
Of what is p the probability?
Correct!
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).
p is the probability that the results would be replicated if the experiment were conducted
a second time.
p is the probability that the results are not due to chance, the probability that the null
hypothesis (H0) is false.
p is the probability that the results are due to chance, the probability that the null
hypothesis (H0) is true.
