置信水平

Using a large sample independent Z test, It can be inferred that the possibility of the averaged scores overall of two key schools science students which falling into the confidence intervals of (89.78, 91.50) and ( 82.79, 87.63) were 95%, significantly at a higher level.

运用独立大样本Z检验，推断两所重点中学理科学生成绩总体均值依次落入以下置信区间(89.78，91.50)，(82.79，87.63)的可能性为95%，达到显著性水平α=0.05。

Physiological Responses of Hybrid Striped Bass to Aqueous Copper copper is an abundant trace metal, and although essential at low levels, it is also potentially toxic to aquatic organisms.Mechanisms of toxicity and consequences of exposure vary depending on ionoregulatory status(acclimated to freshwater or salt water).The goal of this research was to examine the responses of hybrid striped bass(Morone chrysopsXMorone saxatilis)exposed to Cu in freshwater and 15g/L salt water.In freshwater,a general dose-and time-dependent pattern of increasing Cu accumulation in gill tissue was evident in fish exposed to aqueous Cu(220 and 447 mg/L)for up to 96 hours.The 96-horu acute median lethal concentration for freshwater-acclimated hybrid striped bass exposed to Cu was 94mg/L(confidence interval=62 to 144mg/L).

生理反应到水的混合条纹鲈鱼铜是一个丰富的微量金属，虽然至关重要，它是在较低的水平也可能对水生生物有毒毒性机制及其后果的曝光取决于ionoregulatory状态，本研究的主要目的是为了检查的反应chrysopsXMorone混合条纹鲈鱼暴露于铜在淡水和15 / L盐水在淡水，一般dose-and时变模式日益增长的铜积累鱼鳃组织显然暴露于含水的铜(220和447毫克/升)长达96小时96-horu致命的平均浓度为freshwater-acclimated急性混合条纹鲈鱼暴露于铜被94mg / L(=置信区间来144mg / L)62 osmolatity、钠浓度降低。

In other words, if you use an α level of .01, you will fail to reject the null hypothesis, and your confidence interval would contain the null value.

换句话说，如果你使用α水平为。01，你就不能拒绝零假设，你的置信区间将包含零值。
