Final Answer :
B
Explanation :
The t value in this case (t(26) = 3.13) is greater than the critical t value at p < 0.05 for a two-tailed test with 26 degrees of freedom. Therefore, we reject the null hypothesis and conclude that there is a significant difference between the two groups being compared.
