You can just say, OK, for each xi I just perform this operation.

你可以说，好的，对于每个 xi 行这个操作。

And what we want to do is write this right here just in terms of xi's.

们要做的就是在这里用 xi 的形式写下来。

So you take each of the data points in the population-- xi.

因此，您获取总体中的每个数据点 - xi。

I plug in the actual data, the XIs.

插入实际数据，即 XI。

Edit, Undo, minus 2 times mu times the sum from i is equal to 1 to n of xi.

编辑，撤消，减去 2 乘以 mu 乘以 i 的和等于 xi 的 1 到 n。

The songs can also be translated, but they communicate emotionally whether xi or not the words are understood.

歌曲也可以翻译，但无论歌词是否被理解，它们都传达情感。

And it turns out my problem set up, the XIs are normal is too strong of a statement.

事实证明，的问题设置，XI 是正常的，这太强烈了。

If the xi's were normally distributed, this just happens.

如果 xi 是正态分布的, 这种情况就。

If the xi's are not normally distributed, this eventually happens.

如果 习 不是正态分布的，这最终。

So this is p to the sum of the xi's plus alpha minus 1.

所以这是 p 与 xi 的总和加上 alpha 减去 1。

1 Minus p to the n minus sum of the xi's plus beta minus 1.

1减去p到n减去xi的和加上β减去1。

We see some xi's from a Bernoulli distribution.

们从伯努利分布中看到了一些xi。

So this looks like some of the xi's plus alpha over n plus alpha plus beta.

所以这看起来像一些 习 加 alpha 超过 n 加 alpha 加 beta。

The letters came ahead of Xi's upcoming state visit to Brazil, where he will also attend the 19th G20 Summit in Rio de Janeiro.

这些信件是在习即将对巴西进行国事访问之前布的，他还将在那里参加在里约热内卢举行的第 19 届 G20 峰。

For p, given all of my data, this is going to be proportional to n choose some of the xi's.

对于 p，给定的所有数据，这将与 n 选择一些 习 成正比。

What's the sampling distribution for all of the xi's?

所有xi的抽样分布是什么?

Exactly, if all these xi's are independent.

确切地说, 如果所有这些xi都是独立的。

But keep in mind, the xi's are not independent.

但请记住, 习不是独立的。

And all of the xi's is n-dimensional.

而所有的xi都是n维的。

Xi's underlining of Beijing's consistency in US policy will help respond to the potential uncertainties that may be brought about by Washington in the future, he added.

他补充说，习强调北京在美国政策上的一致性将有助于应对华盛顿未来可能带来的潜在不确定性。
