A representative survey finds that 92% of students who completed weekly practice quizzes passed. Lina completed every weekly quiz. Which conclusion is best supported?

### Why this is right The survey provides relevant statistical evidence from a large, representative group, and Lina fits the group described. That makes passing probable, not certain, which is the characteristic support offered by a strong inductive argument. ### The concept An **inductive argument** uses evidence to make a conclusion likely rather than logically unavoidable. Its strength depends on the quality and relevance of the evidence. A representative survey is more useful than a handful of selected examples because it better reflects the group being discussed. Even a strong inductive conclusion can turn out false; probability is not a guarantee. ### The other options - **B. Lina must pass because the argument is deductively valid.** The survey leaves a chance of failure, so the inference is not a deductive guarantee. - **C. Every student who completes quizzes will pass.** This turns a statistical pattern into an absolute claim. - **D. The survey proves quiz completion causes passing.** A reported association does not by itself establish causation. ### Terms - **Inductive argument**: Reasoning that makes a conclusion probable rather than certain. - **Representative**: Reflecting the broader group being studied. - **Deductively valid**: Having a form in which true premises guarantee the conclusion. ### Remember Strong statistical evidence supports “probably,” not “must.”
