Question

Accenture, a global management consulting firm, reported the results of a survey in which Internet buyers in a number of different regions of the world were sampled. Sharp differences in consumer response across regions were found. For example, in Asia, 77% of the survey respondents expressed fears about shopping on the Internet, while only 41% of North Americans shared this concern (source: Shopping for Global Internet Customers: The Case for a Regional Approach, accenture.com). If the sample size was 500 in each region, build and interpret the 95% confidence interval estimate of the difference in the proportion of Internet shoppers who have fears of shopping on the Internet in the two populations represented.
