Answer to Question 1
A paired-samples t-test is an appropriate test for comparing the scores of two interval variables drawn from related populations. This is the appropriate test when the same respondent is measured twice. For example, respondents may be asked their attitudes toward corporate sponsorship in sports and their attitudes toward corporate sponsorship of the arts. Since the attitude scores are both provided by the same person, the assumption that they are independent is not realistic. When a paired-samples t-test is appropriate, the two numbers being compared are usually scored as separate variables.
