If that probability is low, then you can reject the null hypothesis that the mean is the best predictor and, correspondingly, gain confidence that a simple linear model offers a good fit for the data.

第一种可以考虑的方法是对XML文档修改使用“零案例”(或者从科学上说,是“空假设”,从哲学上说,是“第一法则”)。
For exploratory or phenomenological research, you may not have any hypotheses. (Please do not confuse the hypothesis with the statistical null hypothesis.)
对于探索性或现象解释型的研究,你可能不会有任何假说。
We would like to reject H0 (recall that in statistical hypothesis testing rejection of Null hypothesis is always a strong conclusion),thereby demonstrating that the process is capable.
我们想要否定H0(取消对统计的假设中无效力假设的测试否定一直是一个强大的结论)。因此,示范加工是有能力的。

Most statisticians would not argue if you decided to reject the null hypothesis that the results can be accounted for in terms of random sampling variability from the null distribution.
如果您决定排除虚假设—结果可以按照零分布的随机抽样可变性获得,那么大多数统计师都不会有争议。
To test your null hypothesis, you want to know the probability of obtaining a value this extreme under the assumption that it is due to random sampling variability.
要检验虚假设,需要知道在假设存在随机抽样可变性的情况下获得这么一个极限值的概率。
It tells you when to reject the null hypothesis, but it does not tell you whether to accept the alternative hypothesis.
它告诉您何时不采用无效假设,却没有告诉您是否接受备择假设。

This means that the threshold for retaining the null hypothesis explanation was exceeded.
这意味着超出了保持虚假设说明的阈值。
Conclusion: We should reject the null hypothesis.
结论:我们应该拒绝零假设。
In statistical terminology, this sampling variability explanation is called the null hypotheses. (the null hypothesis is designated by the symbol Ho.)
在统计学术语中,这个抽样可变性说明被称为虚假设(null hypothesis)。
In the case of this beer poll, the expected frequency under the null hypothesis is the following.
在这个啤酒欢迎度民意测验的示例中,在虚假设条件下的期望频率如下。
This test-the-null-hypothesis-first logic applies at multiple stages in the analysis of poll data.
这个“先检验虚假设”逻辑在民意测验数据分析中的多个阶段都适用。
This means that the probability of observing a Chi Square value as extreme as 9.80 under the null hypothesis is 2 percent (which is quite a low probability).
这意味着,在虚假设条件下,观察到X平方分布极限值 9.80的概率是 2%(这是一个相当低的概率)。
If you can rule out the null hypothesis, then you will make some progress towards answering the original question about whether Keith's is the most popular brand.
如果您能够排除虚假设,那么您在回答Keiths是否是最受欢迎品牌这个最初的问题上取得了一些进展。
Conclusion: We are unable to reject the null hypothesis.
结论:我们无法拒绝零假设。
This tool is used to test the null hypothesis that there is no difference between two population means against either one-sided or two-sided alternative hypotheses.
此工具用于检验两个总体平均值之间不存在差异的空值假设,而不是单方或双方的其他假设。

Under null hypothesis, the limit distributions of statistics are obtained.
