In 2017, Twitter was the fourth most used social media platform around the world. Statista.com provides estimates of the number of Twitter users (i.e., adults) in various countries in 2017 as well as the projections for 2022. Assume that the results for surveys in the United Kingdom, Canada, and the United States are as follows.

1. Conduct a hypothesis test to determine whether the proportion of adults using Twitter is equal to all three countries. What is the p-value? Using a .05 level of significance, what is your conclusion? (1 pt.)
2. What are the sample proportions of each of the three countries? Which country has the largest proportion of adults using Twitter? (0.5 pts)
3. Using a .05 level of significance, conduct multiple pairwise comparison tests among the three countries. What is your conclusion? (0.5 pts)
