The t statistic falls outside of the cutoffs for a two-tailed test with a significance level of .05, indicating that the results are unlikely to have occurred by chance. Therefore, the null hypothesis (that there is no significant difference between the paired samples) is rejected in favor of the alternative hypothesis.
