Worldwide survey. GfK Roper surveyed people worldwide, asking them, “How important is acquiring wealth to you?” Of 1535 respondents in India, 1168 said that it was of more than average importance. In the United States, of 1317 respondents, 596 said it was of more than average importance.

a) What proportion thought acquiring wealth was of more than average importance in each country’s sample?

b) Create a 95% confidence interval for the proportion who thought it was of more than average importance in India. (Be sure to test conditions.) Compare that to a confidence interval for the U.S. population.
