Which of the following statements regarding p-value is FALSE?
Group of answer choices
A. It is the probability of the observed test statistic or one more extreme, assuming the null is true.
B. The smaller the p-value, the less likely that the observed difference was due to random chance.
C. p-values do not indicate the magnitude or importance of the observed difference.
D. Big p-values provide strong evidence against the Null hypothesis.

Choose the correst answer(s) on questions 1-5 (Please Help) Question 1 Which of the following statements is true? (Select all correct answers) If the mean of two groups remains the same, the P value will not change even if the sample size (n) of those two groups changes.

Examine the following statements. a. The p-value forms the borderline between significance levels that would result in rejecting the null hypothesis and significance levels that would result in not rejecting the null hypothesis. b. The smaller the p-value, the stronger the evidence is in favor of the null hypothesis. c. The p-value is calculated under the assumption that the alternative hypothesis is true.
