Question
Chapter 11.4, Problem 16E
(a)
To determine
To find: whether the study is a randomized comparative experiment or not
(a)
Expert Solution
Answer to Problem 16E
Yes, the study is a randomized comparative experiment
Explanation of Solution
Given:
Calculation:
Yes, the study is a randomized comparative experiment, as here the subjects (voters) are randomly divided into two groups, and are randomly assigned to the control group (with no adds)or the treatment group(with adds).
Conclusion:
Yes, the study is a randomized comparative experiment.
(b)
To determine
To describe: the treatment.
(b)
Expert Solution
Answer to Problem 16E
The treatment here is watching TV with ads for candidate b.
Explanation of Solution
Calculation:
The treatment here is watching TV with ads for candidate b.
Conclusion:
The treatment here is watching TV with ads for candidate b.
(c)
To determine
To conclude: the political advertisements were effective.
(c)
Expert Solution
Answer to Problem 16E
No, it is not concluded that the political advertisements were effective.
Explanation of Solution
Calculation:
No, it is not concluded that the political advertisements were effective because the increase in preference for candidate B with the ads is too small to be significant.
Conclusion:
No, it is not concluded that the political advertisements were effective.
