QUESTION 12 The p-value is the same as the Z statistic measures the number of standard deviations from the mean is a distance is a probability QUESTION 13 For a two tail test, the p-value is the probability of obtaining a value for the test statistic more extreme than that provided by the sample less extreme than that provided by the sample more extreme than that provided by the population less extreme than that provided by the population QUESTION 18 Which of the following does not need to be known in order to compute the p-value? knowledge of whether the test is one-tailed or two-tailed the value of the test statistic the level of significance None of these alternatives is correct.

Step 1
So the correct answer is: $\boxed{\text{probability}}$ For Question 13, in a one-tail test, the p-value is the probability of obtaining a value for the test statistic more extreme than that provided by the sample. So the correct answer is: Show more…

question 14 Find the P-value for the indicated hypothesis test with the given standardized test statistic, z. Decide whether to reject for the given level of significance . Right-tailed test with test statistic z 1.44 and P-value0.02 (Round to four decimal places as needed.) State your conclusion. p value = conclusion failed to reject ho reject ho

QUESTION 15 Whenever hypotheses are established such that the alternative hypothesis is "μ > 8", where μ is the population mean, the p-value is the probability of observing a sample mean greater than the observed sample mean assuming that μ = 8. True False QUESTION 16 Whenever hypotheses are established such that the alternative hypothesis is "μ ≠8", where μ is the population mean, the hypothesis test would be a two-tailed test. True False QUESTION 17 Which of the following does not need to be known in order to compute the p-value? knowledge of whether the test is one-tailed or two-tailed the value of the test statistic the level of significance None of these alternatives is correct.

If the test statistic is greater than the critical value in absolute terms, we will ________. reject the alternative hypothesis cannot determine reject the null hypothesis and accept the alternative hypothesis fail to reject the null hypothesis What is the p-value of a two-sided One-Sample Z-Test for Mean where the z-statistic equals -2.03? 0.0424 0.9788 0.0212 0.9576
