12) Which of the following statements is false regarding the t-test for the regression slope? A. The degrees of freedom for the t test statistic are based on the sample size. -0 is the null hypothesis Rejecting the null hypothesis indicates that there is no significant linear relationship between the two variables. C. None of the above.

Factors Affecting Power in the t Test After completing this week's assigned readings, discuss one of the following questions: What things can a researcher do to try to increase the magnitude of the d effect size? Suppose that you can increase the d effect size while holding group sizes n1 and n2 constant. How will an increase in d influence the magnitude of t ? Several factors influence statistical power for a one-sample t test. How does statistical power change...

In this exercise we examine the effect of the sample size on the significance test for comparing two proportions. In each case suppose that p̂1 = 0.65 and p̂2 = 0.45, and take n to be the common value of n1 and n2. Use the z statistic to test H0: p1 = p2 versus the alternative Ha: p1 ≠ p2. Compute the statistic and the associated P-value for the following values of n: 40, 50, 60, 80, 380, 480, and...

What is an advantage of using a related-samples t-test over an independent-samples t-test? There is a carry-over effect with the related-samples t-test .None of the options. The related-samples t-test needs less participants. There is a maturation effect in the related-samples t-test.
What can be said about the relationship between the significance and the effect size of a...
What can be said about the relationship between the significance and the effect size of a hypothesis test? Group of answer choices The significance of a test is not determined by the effect size alone. A significant test result leads to a large effect size while a non-significant test result leads to a small effect size. The effect size is determined by the alpha level while the significance of a test is not. The effect size is always the same...
