A statistical test is performed, and its P-value turns out to be about 3%. Which of the following must be true? Pick all that are correct.

a) The null hypothesis is true.

b)There is about a 3% chance that the null hypothesis is true.

c) The alternative hypothesis is true. d) There is about a 97% chance that the alternative hypothesis is true.

e) If the null hypothesis were true, there would be about a 3% chance of getting data that were like those that were observed in the sample or even further in the direction of the alternative.

f) The P-value of about 3% was computed assuming that the null hypothesis was true

Correct is only a?

F is definitely true, since it essentially repeats your data.

The rest depend on what critical value you are using to reject the null hypothesis. The most commonly used are P≤.05 or P≤.01.
