The Alternative Hypothesis

You can use a statistical decision procedure to reject the alternative hypothesis that a straight line fits the data.

可以使用统计决策过程来否决“直线与数据吻合”这个备择假设。

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。
