Question: As markets become more and more international, many firms invest in research aimed at determining the maximum possible extent of sales in foreign markets. A U.S. manufacturer of coffeemakers wants to find out whether the company's market share and the market shares of two main competitors are about the same in three European countries to which all three companies export their products. The results of a market survey are summarized in the following table. The data are random samples of 150 consumers in each country. Conduct the test of equality of population proportions across the three countries.
