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...
