A confidence interval for a sample is given, followed by several hypotheses to test using that sample. In each case, use the confidence interval to give a conclusion of the test (if possible) and also state the significance level you are using. (a) Ho: P1 = P2 VS Ha: P1 P2 Conclusion: Significance level: (b) Ho: P1 P2 VS Ha: P1 P2 Conclusion: Significance level: Но Conclusion: (c) Ho: P1 = P2 VS Ha: P1 P2 Reject Significance Do not reject Но Но A 90% confidence interval for p₁ - P₂: 0.04 to 0.19
