Description: Which of the following is the correct interpretation of these paired-samples T test results?A. time 1 scores are significantly higher than time 2 scoresB. time 2 scores are significantly higher than time 1 scores.C. time 1 scores are not significantl

in paired t test we compares the means of two paired groups. which mean we check the difference between two means of paired data. hence from the above summary table we first check the means of time 1 and time 2. time 1 have greater mean than time 2. hence mean difference is > 0. hence the correct interpretation is A. time 1 scores are significantly higher than time 2 scores
