Ten randomly selected people took an IQ test A, and next day they took a very similar IQ test B. Their scores are shown in the table below.
Person A B C D E F G H I J
Test A 100 108 113 78 97 107 95 129 90 84
Test B 102 112 113 78 100 110 95 129 92 84
- Consider (Test A - Test B). Use a 0.05 significance level to test the claim that people do better on the second test than they do on the first. (Note: You may wish to use software.)
