Based on the table, with 25 degrees of freedom and a significance level of 5%, the critical value is 2.06. However, because the sample size is greater than 20, a more accurate critical value can be found by interpolating between the values in the table. Interpolating between 20 and 30 degrees of freedom and between 2.5% and 1%, the critical value is approximately 2.87, which is closest to choice B.
