There are problems that we call hypothesis testing problems.

有些问题我们称之为假设检验问题。

Techniques such as hypothesis testing and confidence intervals rely on probability theory.

假设检验和置信区间等技术依赖于概率论。

So for example, in actually all of the hypothesis testing examples we've seen, we start assuming that the null hypothesis is true.

因此，例如，实际上在我们见过的所有假设检验示例中，我们开始假设原假设为真。

When we produce thin section slides, We are choosing specimens based on a question that we're asking or a hypothesis that we're testing And the next bone on the chopping block is going to maybe fill in a piece of the puzzle.

当我们制作薄切片幻灯片时，我们是根据我们提出的问题或我们正在测试的假设来选择样本， 而砧板上的下一块骨头可能会填补一块拼图。
