In a research context, the alternative hypothesis of a linear model needs to be established by theoretical and statistical arguments.

在研究环境中，需要通过理论参数和统计参数来建立线性模型备择假设。

In single-side hypothesis testing, the exchange of the null hypothesis and alternative hypothesis would induce two different testing results sometimes.

在单侧检验中，有时由于交换原假设与备择假设，会得到两个不同的假设检验结果。

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。

The alternative hypothesis that you can then entertain is that the proportions are different in the population of interest.

那么，另一个可接受的假设是在所研究的总体中，各种回答所占比例不同。

The alternative hypothesis -- that a difference in proportions exists in the population -- is statistically more likely to be true.

另一种假设 — 对象总体中存在着比例差异 — 在统计上可能更正确。
