置信区间

To provide auxiliary decision making support, a judgment method of simulation test result is presented based on confidence interval, and risk function of statistics decision-making is discussed.

为提供辅助决策支持，提出了基于置信区间的仿真试验结果决策方法，并讨论了统计决策的风险函数。

In either case, the interval or the definition of closeness should be specified in the validation protocol.

在每一情况下置信区间或紧密度的定义应在验证方案中指明。

Chimera2 and 4 were similar to the langshan chickens separately on the performance of dustbathing and standing, while the behavioral pattern of the other three chimeras were close to the recipient.

比较发现，嵌合体1的这些行为的发生频率都位于狼山鸡相应行为平均值的95％的置信区间之內，其行为模式倾向于供体狼山鸡，嵌合体2和6分别在洗浴和站立行为的发生频率上与供体狼山鸡相似，而其他3只嵌合体鸡的行为模式却与受体AA肉鸡接近。

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。

Consistency of change-point estimator is proved and its rate of convergence is established under weak assumptions. To construct confidence interval, the limiting distribution of change-point estimator is obtained.

在较弱的条件下证明了变点估计的一致性，并得到了佑计的收敛率；为构造变点的置信区间给出了变点的极限分布。

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。

Compared with nonuse, warfarin use associated with a significantly increased risk for new stroke (hazard ratio 1.93; 95% confidence interval 1.29 to 2.90); clopidogrel or aspirin use did not associate with increased risk for new stroke.

与不应用这些药物相比，应用华法令患者新发中风风险显著增加（危害比1.93； 95%置信区间 1.29 - 2.90），两者相关；应用氯吡格雷或阿司匹林与新发中风风险增加不相关。

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。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
