Using a two-tailed test with a sample size of 20 and α = .20, we need to find the critical value of t. From the t distribution table with 18 degrees of freedom (n-1=20-1=19, and α/2 = .10), we find the critical value to be 1.734. Since the sample size is small, we round this value to 1.34. However, since we are dealing with a two-tailed test, we need to consider both positive and negative critical values. Thus, the critical values are ±1.341, which is closest to choice A.
