Answer:
b) It is calculated from the data that was collected.
Explanation:
We know that the p-value is calculated by using the given test statistic value and the distribution used in the hypothesis test. So, the test statistic is calculated from the collected data and therefore the p-value is calculated from the data that was collected.

The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject He when the level of significance is (a) a = 0.01, (b) a = 0.05, and (C) a = 0.10. P = 0.0695 (a) Do you reject or fail to reject He at the 0.01 level of significance? O A. Fail to reject H, because the P-value, 0.0695, is greater than a = 0.01. O B. Fail to reject H, because the P-value, 0.0695,...

If the p-value = 0.4567, then which of the following is true. A. We fail to reject Ho at a significance level = .05 B. We fail to reject Ho at a significance level = .10 C. We fail to reject Ho at a significance level = .01 D. All of these answers are correct When choosing between a biased but very efficient estimator and an unbiased but very inefficient estimator, we should choose the one with the minimum Mean...

Which of the following is TRUE? a. The p-value should always be larger than the selected level of significance. b. If the p-value is smaller than the level of significance, then do not reject the alternate hypothesis. c. If we reject the null hypothesis, it is possible that p-value is larger than the selected level of significance. d. If the p-value is larger than the level of significance, then do not reject the null hypothesis.
