.1 Exploring Matrix Multiplication The table shows the first two test scores for Anna, Bruce, Chris, and David. Use the table to create a 4x2 matrix M to represent the data. This is Project 2.1 in your textbook. Test 1 Test 2 Anna 84 96 Bruce 56 72 Chris 78 83 David 82 91 1. Which test was more difficult? Which was easier? Explain. 2. How would you rank the performances of the four students? 3. Describe the meanings of the matrix products M [] 1 0 and M 1 4. Describe the meanings of the matrix products [1000] and [0 0 1 0] M. 5. Describe the meanings of the matrix products M 1 1 and M 2 1 - [1111]M and [1111] M. || 6. Describe the meanings of the matrix products [1 [1111] M and 7. Describe the meaning of the matrix product [1 1 1 1 8. Use matrix multiplication to find the combined overall average score on both tests. 9. How could you use matrix multiplication to scale the scores on test 1 by a factor of 1.1?
