请以资深中国数学教师的身份，解析图片上习题的答案，要求讲解过程图文并茂，用不同的颜色标注，语言风格风趣幽默，简单易懂。---**Textual Information:** 7. 假设检验与区间估计的关系: (检验统计量与枢轴量相同). 置信度为 1-α 的双侧置信区间与显著性水平为 α 的双侧检验问题是一一对应的. 【例9.6】 设 α 为显著性水平, β 为置信水平, 若 λ 为 T 统计量的临界值, 则 α = P{__________}, β = P{__________}. **Chart/Diagram Description:** * **Type:** A sketch of a probability density function curve (bell shape, likely representing a t-distribution or normal distribution) with a horizontal axis and a vertical axis. * **Main Elements:** * **Curve:** A unimodal, symmetric curve peaking at the vertical axis. * **Horizontal Axis:** Representing the range of the statistic's values. It has tick marks and labels indicating specific values. * **Vertical Axis:** Labeled with an upward arrow, likely representing the density. * **Labeled Points/Regions:** * Two vertical lines on the horizontal axis are marked, symmetric about the vertical axis. * The left mark is labeled "-λα/2". * The right mark is labeled "λα/2". * The regions under the curve to the left of -λα/2 and to the right of λα/2 are shaded or marked with hatching, indicating tail areas.
