How well can you type with your eyes closed? A study was conducted using 6 adult volunteers who are proficient at typing. Each volunteer was given two tests. Test A required each volunteer to type 100 words that were written on a piece of paper. Test B required each volunteer to type 100 words while blind-folded. During this test, the volunteers put on headphones and heard the words being read to them from a recording. The order in which the tests were given were randomized for each volunteer. The table below shows the number of words each volunteer typed correctly as well as the difference (A-B) in the number of words typed correctly. Volunteer Test A (Vision) Test B (No vision) Difference (A-B) 12 3 4 5 6 82 54 77 58 94 85 78 53 64 46 88 88 1 13 12 6-3 Do these data provide convincing evidence at the a=0.10 level that the number of words that adult volunteers like these would type correctly using these two tests differs, on average?
