The t Test for Two Related Samples Graded Assignment | Read Chapter 11 Due Sunday 07.0118 at 11:45 P Attempts: Average: /1 7. Assumptions underlying the repeated-measures t test Aa Aa B Individuals with a condition known as "prosopagnosia" cannot recognize faces. Their perceptual abilities are intact, and they can accurately describe features such as eye color, size of the nose, and shape of the mouth. They can even tell you whether someone is attractive. However, they cannot recognize anyone's face, not even the faces of their friends and family. Dr. Joseph DeGutis has been conducting research and trying to develop a training regimen that would allow patients with prosopagnosia to improve their recognition abilities. Patients complete a battery of perceptual tests to determine their baseline performance (a pre-test) and then are trained for 6 days on a facial categorization task. They are tested again (a post-test) to determine their levels of improvement. Would it be valid for Dr. DeGutis to use the repeated-measures t test to test whether the training leads to an improvement? O Yes, for any sample size. O No, because his design uses independent groups. O No, because the two sample sizes are not equal. O Yes, if his sample size is 230 or the raw scores are normally distributed
