Do unionized workers donate to political campaigns more often than non-unionized workers? To find out, we collect data from a random sample of 150 unionized workers and 150 non-unionized workers in Ontario. If 97 of the unionized and 86 of the non-unionized workers donated to a political party in the last federal election, which test would be appropriate to determine if we have evidence to support this claim?

• A. Two-tail t-test
• B. Chi-squared test
• C. Correlation
• D. One-tail t-test
