Chapter 9 homework 2. What value is in the dominator in each of the equations of the z and t test? Is this mathematically the only thing that is different between the two equations? 4. What does a negative value for the t test mean? 6. What are the three bits of information that the t table needs in order to use it? 10. a. Perform a test with the following scores: Population mean = 94, M=100 and the SEM=7. b. Consult the t table to obtain a critical value for the outcome using an alpha level of a=.05, for a two tailed test and with a degree of freedom of df=7. c. Would the t value you got be significant if doing a true test? 12. What are the three parts of the t test (or any statistical test) that you need to report when using APA standards? 18. A school psychologist wanted to test if children at their school make more or less racist remarks than the average found in the population, which is u=7 and a SD=2. They observed 10 classes and counted the number of racist remarks that the children made in their school. The following is the raw scores from their observations: 4, 2, 8, 5, 3, 6, 5, 3, 1, 7. The alpha level for the study was set to a=.05 for the criteria. a. State the hypotheses of the study. b. Find the critical t value for this study c. Compute the one sample t test d. State the results in APA format (numbers and words) and don't forget to include all parts in the sentence and the direction of the results
