Or an interval of-- we have a confidence interval.

或者一个区间——我们有一个置信区间。

What we now need to do is actually tackle the confidence interval.

我们现在需要做的实际上是解决置信区间问题。

Or what is a confidence interval of the difference of means?

或者均值差异的置信区间是多少？

And that's why we just say it's a confidence interval.

这就是为什么我们只说这是一个置信区间。

So what we want to do when we want a confidence interval, we want to be confident.

所以当我们想要一个置信区间时，我们想要做什么，我们想要有信心。

And the margin of error is just another way of describing this confidence interval.

误差幅度只是描述此置信区间的另一种方式。

Summary measures of uncertainty, so that's comparing here confidence intervals, with credible intervals. And the next part of the book, I start off.

对不确定性的测量进行总结 比较置信区间和可信区间 书的下一部分 我开始了。

Because here we have this confidence interval for this weird mean of the difference between the sampling means.

因为这里我们有这个采样平均值之间差异的奇怪平均值的置信区间。

But when we construct it this way, it becomes pretty clear, how do we actually construct the confidence interval?

但是当我们以这种方式构造它时， 就很清楚了，我们实际上是如何构造置信区间的？

The second part, how could the survey be changed to narrow the confidence interval, but to maintain the 99% confidence interval?

第二部分，如何改变调查来缩小置信区间， 但保持99%的置信区间？

So if we want our confidence interval, our actual number that we got for there, our actual sample mean we got was 0.568.

所以如果我们想要我们的置信区间，我们在那里得到的实际数字， 我们得到的实际样本平均值是 0. 568。

And because I'm trying to make my best effort not to make videos too long, I'll do part two in the next video, where we actually solve the confidence interval.

因为我正在尽最大努力不让视频太长，所以我将在下一个视频中进行第二部分，我们将在其中实际求解置信区间。
