Explanation:

To perform a two - sample t - test, the correct order of steps is: first, state the hypotheses and identify the claim. Then, specify the level of significance. Next, determine the degrees of freedom. After that, find the critical value(s) and identify the rejection region(s). Then, find the standardized test statistic. Finally, make a decision and interpret it in the context of the original claim. Option C follows this correct order of steps for conducting a two - sample t - test.

Answer:

C. State the hypotheses and identify the claim. Specify the level of significance. Determine the degrees of freedom. Find the critical value(s) and identify the rejection region(s). Make a decision and interpret it in the context of the original claim.
