A)A related samples t test is the correct tests for this study;the result of the test is not significant
B)A related samples t test is the correct tests for this study;the result of the test is significant
C)The result of the test cannot be appropriately interpreted because the related samples t test was not the correct test for this study;the researcher should have computed a two-independent sample t test
D)The result of the test cannot be appropriately interpreted because the related samples t test was not the correct test for this study;the researcher should have computed a one-sample t test

Since the related samples t test was the appropriate test for this study and the obtained t value (2.68) is significant at .05 level of significance, it implies that there is a significant difference between the observed behaviors of the participants at two different times. The null hypothesis can be rejected, and the alternative hypothesis can be accepted.
