15. Which of the following statements are true about a Z test? O F. A, B C, and D are correct. C. If the P value from the test exceeds 5%, we fail to reject the null hypothesis. A. The test determines statistical significance. B. The two tailed P value is obtained by calculating a sample Z score by the formula, Z score = (point estimate - null value) / (standard error of point estimate), and looking up the corresponding probability of randomly obtaining an equal or greater absolute value of Z in a table of the standard normal distribution. E. Only A, B and C are correct. D. If the absolute value of the Z score exceeds 1.96, then the P Value is greater than 5%.
