In country B, of 1326 respondents, 597 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 99% confidence interval for the percentage of people who thought it was of more than average importance in country A. (Be sure to test conditions.) Compare that to a confidence interval for the country B population. for country B. a) The sample proportions are for country A and Round to three decimal places as needed.) b) What is the confidence interval for country A? Select the correct choice below and, if necessary, fill in the answer boxes within your choice A. (KOs) The 99% confidence interval for country A is (Round to one decimal place as needed.)

Explanation / Answer

a) P for A = 1137/1524 = 0.746

P for B = 597/1326 = 0.450

b) The 99% confidence interval for p is: 0.7 < p < 0.8

c) Conf interval for B:

The 99% confidence interval for p is: 0.415<p<0.485

Thus,

A option
