1. For a T distribution with 10 degrees of freedom, what is the probability P(T < -1.372)? 1. We consider a sample of 11 being used in a hypothesis test. In a two-sided hypothesis test where we reject if the value of |To| > Ta/2 is -2.05. Do you reject the null hypothesis in this case (explain why)? What is the p- value in this case (you may use a range for the p-value)? 2. This time a sample size...

8. Degrees of freedom for chi-squared tests are determined by sample size. True or False 7. If a correlation between two variables is negative, that means there is no linear relationship between them. True or False 2. For a chi-square test, if the observed number of cases in your sample fits what you expect given your knowledge of the population, you would reject the null hypothesis. True or False 1. A two-tailed hypothesis will have more statistical power than a...

As degrees of freedom (df) increase, the t distribution cannot be measured approaches the distribution of raw scores becomes more symmetrical approaches the standard normal distribution You perform a two-tailed t-test with an α = .05 comparing the average reaction time to blue and red stimuli. You find that the average reaction time for blue stimuli is M = 5.3 ms and the average reaction time to red stimuli is M = 4.2 ms. The probability value for your t-test...

When accounting for income taxes, the differences between financial accounting and taxation accounting creates permanent and...
When accounting for income taxes, the differences between financial accounting and taxation accounting creates permanent and temporary differences between the expenses and liabilities reported under each regime. Why do these differences exist? What are the reasons that explain why we have one system of accounting for financial reporting, and a second for taxation? Please give an in-depth explanation for the various reasons for why there are two systems for this, instead of one. I am looking for a general explanation...
