(1 point) Book Problem 9 Each of the following statements is an attempt to show that a given series is convergent or divergent. For each statement, enter C (for "correct") if the argument is valid, or enter I (for "incorrect") if any part of the argument is flawed. (Note: if the conclusion is true but the argument that led to it was wrong, you must enter I.) 1. For all n > 3, and the series E converges. n2 2 72 1 So by the Comparison Test, the series converges. 2 2. For all n > 1, and the series E 7 2 converges. n2 + n + 2 n2 So by the Comparison Test, the series E converges. n2 + n + 2 Vn +1 3. For all n > 1, and the series n n - diverges, So by the Comparison Test, the series E n + 1 diverges. n
