So this critical Z value is equal to 1.65.

所以这个临界 Z 值等于 1.65。

We're getting a result above that Z value, only has a 5% chance.

我们得到的结果高于 Z 值，只有 5% 的机会。

And this gives us Z value of 1.96.

这给了我们 1.96 的 Z 值。

So there's going to be some Z value right over here where we have 2.5% above it.

所以这里会有一些 Z 值，我们比它高出 2.5%。

So when we look at a Z table, we want the critical Z value that they give right over here.

因此，当我们查看 Z 表时，我们需要他们在此处给出的临界 Z 值。

We're not going to look up 95%, because a Z table gives us the cumulative probability up to that critical Z value.

我们不会查找 95%，因为 Z 表为我们提供了达到该临界 Z 值的累积概率。

But if we can find whatever Z value this is right over here, it's going to be the same Z value as that.

但是如果我们能找到这里的任何 Z 值，它就会与那个 Z 值相同。
