We are interested in significant differences (level a = 0.05) between the expected values µ1 and µ2 of two populations. Which of the following statements on statistical tests are correct? a) We will formulate the null hypothesis as µ1 = 42. b) A t-test can always be applied in this situation. c) A p-value is the probability that the null hypothesis is correct, given the observed data. d) If we obtain a p-value of 0.04, we will reject (level a = 0.05) the null hypothesis.
