( .) Each of the following statements is an attempt to show that a given series is convergent or divergent not using the Comparison Test (NOT the Limit Comparison Test.) 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.) √n+1 1. For all n > 2, n by the Comparison Test, the series > sin² (n) n² 2. For all n > 1, so by the Comparison Test, the series 1 n ln(n) by the Comparison Test, the series > 1 n² - 2 so by the Comparison Test, the series > n 5. For all n > 1, 3-n³ so by the Comparison Test, the series 3. For all n > 1, 4. For all n > 2, 6. For all n > 2, 1 n √n +1 n 1 n n³ - 1 so by the Comparison Test, the series > 1 n² sin²(n) n² 1 7² and the series nln(n) 1 n² 2 n² 2 <, and the series 2 = diverges, so n n diverges. , and the series Σ diverges. and the series Σ 1 n² - 2 1 1 1 1 Σ; diverges, so n n 3-n³ converges. n n³ - 1 converges. and the series Σ/1/2 n² converges. and the series 2 n² converges. converges, converges, converges, 1 n² converges,
