The p-value for a two-tailed t-test with 10 degrees of freedom and a t-value of 2.25 is between 0.05 and 0.10. However, in a two-tailed test, we need to consider both sides of the distribution. Therefore, we need to divide the p-value by 2 to get the probability of the t-value being on one side of the distribution. Thus, the p-value for this two-tailed test is between 0.025 and 0.050. Since this range includes 0.05, we can conclude that the results are significant at the 0.05 level of significance.
