Answer to Question 1

B
When the probability that the experimental results are due to chance exceeds alpha, the researcher should conclude that chance is responsible for the results. This would require that the null hypothesis (which states that only chance is responsible and the independent variable did not have an effect) not be rejected.

Answer to Question 2

C
If the probability that the results were due to chance is greater than alpha, the researcher must conclude that chance is responsible for the results and fail to reject the null hypothesis.
