Ten randomly selected people took 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 | 101 | 112 | 99 | 73 | 91 | 113 | 93 | 105 | 124 | 82 |
Test B | 102 | 117 | 98 | 74 | 92 | 110 | 92 | 108 | 125 | 83 |
Calculate (Test B - Test A) to find the differences. Use a = .05
significance level to test the claim that people do better on the
second test than they do on the first. Use Two Dependent Samples
t-test (Matched Pairs) to solve problem.
a. the test statistic is _________?
b. The P value is __________?
I know the excel way to get answer but I need to know work to be prepared for test. Please show as much work as possible so that I can learn from and use for my other problems. Thank you so much.
