26. Suppose an advertising agency was interested in evaluating the effectiveness of a TV ad conducted an experiment using 300 subjects. Half of the respondents were in the control group and did not see the new test ad while the other half did. The correct test would be a:
A) independent sample t-test
B) paired sample t-test
C) cross tabulation
D) multivariate analysis of covariance (MANCOVA)

32. Suppose that an advertising agency was interested in evaluating the effectiveness of a TV ad conducted an experiment using 300 subjects. Half of the respondents were in the control group and did not see the new test ad while the other half did. After the experiment, individuals were asked about their attitude towards the brand and purchase intentions, both used a 5-point scale. To determine if it was significant, researchers should use:
