The critical t-value for a two-tailed test with α=0.05 and 23 degrees of freedom (n-k-1) is ±2.131. This corresponds to a 95% confidence level. The t-value for the null hypothesis test (t-value=β/SE) is not given in the tables, so it cannot be determined whether the null hypothesis should be accepted or rejected.
