A researcher conducts an experiment consisting of two groups—Group 1, non-smokers, and Group 2, ex-smokers. Group 1 consists of 10 participants, while Group 2 has 12 participants. If the researcher conducts a two-tailed two-independent sample t-test, what will the degrees of freedom and the critical values at a 0.05 level of significance be? (Round your critical values to three decimal places.) degrees of freedom critical value (smaller value) critical value (larger value)
