Explain what a P-value is. What is the criterion for rejecting the null hypothesis using the P-value approach? Explain what a P-value is. Choose the correct answer below. O A. AP-value is the probability of observing a sample statistic as extreme or more extreme than the one observed under the assumption that the statement in the null hypothes OB. AP-value is the value used to designate the area a in either the left- or right-tail of the normal curve. OC. AP-value is the number of standard deviations that the observed proportion is from the proportion stated in the null hypothesis. What is the criterion for rejecting the null hypothesis using the P-value approach? Choose the correct answer below. O A. If P-value a, reject the null hypothesis. Oc. If P-value <-z, for a left-tailed test, or if P-value > za for a right-tailed test, or if P-value < - Za/2 or P-value > z/2 for a two-tailed test, then reject the null hypothesis.
