8. Suppose a researcher wants to see whether teaching students to read using a computer game gives better results than teaching with a tried-and-true phonics method. She randomly selects 20 students and puts them into 10 pairs according to their reading readiness level, age, IQ, and so on. She randomly selects one student from each pair to learn to read via the computer game, and the other learns to read Using the phonics method. At the end of the study, each student takes the same reading test. The data are shown in the following table. 2 3 45 8 9 Student Pair 1 6 7 10 78 82 57 69 Reading Score under 73 99 85 80 95 Computer Method Reading Score under phonics method 30 80 88 90 72 79 50 73 78 95 Test whether there is a significant difference between the computer method and the phonics method. If there is a significant difference, which particular method is better? 9. Aschool psychologist is interested in whether or not teachers affect the anxiety scores among students taking the Statistics exam.
