If the Cl for p; po does not include 0, it suggests a statistically significant difference between the proportions; hence Bis true. Confidence intervals are indeed used to estimate the difference between two proportions; C is true. Hypothesis testingnot confidence intervalsis the formal method used to test a claim about two population proportions (although a Cl can informally suggest significance). Therefore D is the statement that is NOT true. Ask Al your follow up question. Do not enter personal information
