The probability of generating a test statistic as or more extreme as the one observed given that the null hypothesis is true. ii. Rejecting the null hypothesis when the null hypothesis is true. iii. Failing to reject the null hypothesis when the null hypothesis is false. iv. The probability of rejecting the null hypothesis when the null hypothesis is true. b) If a given P-value' 18 less than a, this suggests that (indicate all that apply). i. The probability of experiencing the result we experienced is beyond our threshold for it being due to random chance. ii. The probability of experiencing the result we experienced is not beyond our threshold for it being due to random chance. iii. We should fail to reject the null hypothesis. iv. We should reject the null hypothesis. c) (True / False) The sample variance follows a sampling distribution. d) |(True/ False) If the distribution of Y is normal, then the sampling distribution of 17 will always be exactly normal
