Chapter 25, Problem 3E

(a)

To determine

To describe an experiment design requiring a matched pair t procedure to analyze the results.

Explanation of Solution

In the question researchers want to see that if the presence of sexual images in an advertisement affects people’s ability to remember the product or not. As the ads for many products use sexual images to try to attract attention to the product. Thus, to design an experiment requiring a matched pair t procedure to analyze the results we have to randomly select subjects. And then the half of subjects randomly selected, first view an ad with sexual images and then an ad without sexual images. And then the other half of subjects, first view an ad without sexual images and then an ad with sexual images. Then, we will record how many products they remember in each group. And finally, we will examine the differences for each person.

(b)

To determine

To describe an experiment design requiring an independent sample procedure to analyze the results.

Explanation of Solution

In the question researchers want to see that if the presence of sexual images in an advertisement affects people’s ability to remember the product or not. As the ads for many products use sexual images to try to attract attention to the product. Thus, to design an experiment design requiring an independent sample procedure to analyze the results we have to randomly select subjects. And then half of subjects randomly selected will view an ad with sexual images. And the other half of subjects views an ad with sexual images. And then we will record how many products they remember in each group and compare.
