Which of the following statements is correct?     The p-value measures the probability of obtaining a test statistic as great as or greater than the value of the observed test statistic.     The p-value measures the probability that the hypothesis is true.     The p-value measures the probability of making a Type II error.     The larger the p-value, the stronger the evidence against the null hypothesis     A large p-value indicates that the data is consistent with the alternative hypothesis.
