Question

An experiment was conducted to determine if exposure to an advertisement would change attitude toward a product. Each subject’s attitude before and after exposure to the advertisement was recorded, using a valid ten point scale. The results indicated:

Subject Attitude Post Exposure Attitude Pre Exposure

1 6 4

2 8 5

3 6 6

4 4 3

5 7 2

6 6 3

7 9 6

8 7 6

9 8 5

10 8 6

Set up hypotheses and test to determine if the mean attitude toward the product increased as a result of exposure to the advertisement. (Note: these samples must be regarded as dependent, as each subject served as both a control (pre-exposure) and a treatment (post exposure).
