Answer to Question 1

H0: p1 = .50, p2 = .50 (the coin is fair)
H1: At least one pi is not equal to its specified value (the coin is not fair)
Rejection region: 2 > 2.05,1 = 3.841
Test statistic: 2 = 2.88
Conclusion: Cannot reject the null hypothesis. There is not enough evidence to say the coin is not fair, according to the data.
