Question
Consider the following table that contains the IDs of 12 participants and their crash- avoidance reaction times (in milliseconds) on four tests. Two tests were done during the day in daylight and two tests were done at night with reduced lighting. Crash-avoidance Reaction Time (ms) Participant Day Night ID Test 1 Test 2 Test 3 Test 4 9001 887 838 765 648 9002 680 491 953 767 9003 662 553 985 696 9004 789 526 581 770 9005 508 451 688 714 9006 566 633 856 642 9007 656 747 846 718 9008 776 491 944 604 9009 770 672 814 617 9010 333 432 591 602 9011 730 593 796 700 9012 496 404 846 892 rt.xisx in the This question has multiple parts. Create output to MATLAB's command window exactly as shown, except replacing xxxx with actual values, as instructed. You may use the disp command, but not the fprintf command If you have difficulty with the alignment or formatting of numeric output, add the command format shortg near the top of your solution. In your solution, put the following MATLAB statements at the beginning of each part: % Question 5<x> solution disp('----- q5<x> solution -----'); Instead of "<x>", substitute the question part ("a" for part a, "b" for part b, and so on).
