What style of carpeting do you have in your office?

This question is well formulated, however has little to do with the residential application of designer carpet.

Do you intend to buy a new carpet soon?

This question needs to be more specific in the time frame of carpet purchase, soon is too vague to be useful.

d. Do you believe, as most Americans do, that U.S. citizens should buy American-made carpets?

This question leads the respondent with the phrase "as most Americans," which should be removed.

e. Will you buy designer carpets given that they cost slightly more than traditional carpets?

A choice of "uncertain" should be included, and the question should be rephrased to "Are you likely to by" rather than "Will you buy."

Chapter 12: Question 3:

Stratified random sampling is recommended for this survey, because it divides the population into smaller subgroups prior to drawing the sample. In this way, DuPont can determine if there is any correlation between certain demographic features, such as income level, and answers given.

Chapter 13: Question 2:

A) How large a sample does DuPont need to draw in order to be 99% sure that the result is within 5% of the true value?

A sample of approximately 665 is needed, assuming the population size is approximately 200 million.

B) What if they wanted it to be only within 20% of the true value at a 99% level of confidence?

A sample of approximately 40 is needed, assuming the population size is approximately 200 million.

C) What if DuPont required only an 80% level of confidence at a 20% level of precision?

A sample of approximately 10 is needed, assuming the population size is approximately 200 million.

Chapter 14: Question 4:

To validate field work, a small sample of respondents should be questioned to see if they actually participated in the survey. A small sample of respondents should also be questioned about the length and quality of the interview, as well as their thoughts on the interviewer. Lastly, a small sample of respondent should be re-questioned about their demographic information to check for accuracy for what was reported.

Data for the last 3 questions was not provided, and as the paper is well beyond the 5 pages paid for are not included.
