The critical values for testing a hypothesis about a regression coefficient at a significance level of 0.05 typically come from a t-distribution. The exact critical value depends on the degrees of freedom associated with the regression, which is related to the sample size. Without the specific degrees of freedom or sample size, option B) ±2.7764 is a reasonable choice as it is a common critical value used for small sample sizes (e.g., df = 20) in a two-tailed test at the 0.05 significance level.
