Explanation:
Detailed explanation-1: -If you want the critical value of t for a two-tailed test, divide the significance level by two.
Detailed explanation-2: -A 95% confidence interval would encompass all but the bottom 2.5% and the top 97.5% which correspond to probabilities of 0.025 and 0.975. We can use qt(p, df)to compute the critical value of t. Therefore, the critical value of t is about 2.05.
