Suppose that the survey had a sample size of n=900. Construct a 95% confidence interval estimate for the population proportion of consumers that value personalized experience most when shopping in a retail store? STS (Round to four decimal places as needed.) b. Based on (a), can you claim that more than a quarter of all consumers value personalized experience most when shopping in a retail store? O A. No, because a 95% confidence interval is not indicative of a guarantee. A 99.9% confidence interval would be needed to make such a claim. OB. Yes, with 95% confidence because the sample proportion is greater than a quarter, and it falls within the limits of the confidence interval estimate. v by SAT 11 18

OSTSO (Round to four decimal places as needed.) b. Based on (a), can you claim that more than a quarter of all consumers value personalized experience most when shopping in a retail store? OA. No, because a 95% confidence interval is not indicative of a guarantee. A 99.9% confidence interval would be needed to make such a claim. OB. Yes, with 95% confidence because the sample proportion is greater than a quarter, and it falls within the limits of the confidence interval estimate. OC. No, because the confidence interval contains proportion values that are less than 0.25. OD. Yes, with 95% confidence because all the values contained in the confidence interval are greater than 0.25. c. Repeat parts (a) and (b), assuming that the survey had a sample size of n = 10,000.
