D. No, because a 90% confidence interval is not indicative of a guarantee. A 99.9% confidence interval would be needed to make such a claim.

Answer 1

No, because the confidence interval contains proportion values that are less than 0.25.

Step-by-step explanation:

Based on (a), you cannot claim that more than a quarter of all consumers value personalized experience most when shopping in a retail store. The correct answer is C. No, because the confidence interval contains proportion values that are less than 0.25.

A confidence interval is a range of values that is likely to contain the true population parameter. In this case, the confidence interval was calculated to estimate the proportion of consumers who value personalized experience most when shopping. Since the confidence interval contains proportion values less than 0.25, we cannot claim with confidence that more than a quarter of all consumers value personalized experience most.

Therefore, option C is the correct answer.
