Conduct a hypothesis test to determine whether the proportion of adults using social networking sites is equal for all four countries. Given alpha = 0.05, what is your conclusion? Use both critical and p-value approaches? What are the sample proportions for each of the four countries? Which country has the largest proportion of adults using social networking sites? Using a 0.05 level of significance, conduct multiple pairwise comparison tests among four countries. What is your conclusion?
