And the mean of the population is actually the true population proportion.

而人口的均值实际上就是真实的人口比例。

I don't want to just divided by 100-- remember, I'm trying to estimate the true population mean.

我不想只除以 100——请记住，我正在尝试估计真实的人口均值。

So, my question here is, are the means and the true population means the same?

所以， 我的问题是，均值和真实人口均值是否相同？

We don't know the true population parameters.

我们不知道真正的人口参数。

So my question is " this" equal to " this" equal to the mean 3, the true population of mean 3.

所以我的问题是“这个”等于“这个”等于均值3，均值3的真实人口。

Well, if we assume that the true population proportions are actually the same between men and women.

好吧，如果我们假设真正的人口比例在男性和女性之间实际上是相同的。

This is giving us a confidence interval for the true population means.

这为我们提供了真实总体均值的置信区间。

So that should make us believe that there is a difference in the true population mean.

所以这应该让我们相信真实的人口均值存在差异。

So we are 99% confident that the true population proportion is between these two numbers.

因此，我们有 99% 的把握认为真实的人口比例介于这两个数字之间。

So if P1 is equal to P2, we can just represent them as just some true population proportion.

所以如果 P1 等于 P2，我们可以将它们表示为一些真实的人口比例。

Or that P1 minus P2, the proportion of men voting minus the proportion of women voting, the true population proportions, do not equal 0.

或者P1减去P2，男性投票的比例减去女性投票的比例， 真实的人口比例， 不等于0。

The latest Indian census of the island tried to estimate their population and calculated it to be around 40, but other estimates place the true population somewhere between 50 and 400 people.

印度对该岛的最新人口普查想要估计其人口数量，并计算出大约有 40 人，但其他估计认为真正的人口在 50 至 400 人之间。

The research team says it hopes to start breeding efforts between highland wild dogs and New Guinea singing dogs in captivity to help create " a true New Guinea singing dog population" .

研究团队说它希望能开始人工驯养高地野狗和新几内亚歌唱犬来帮助创造" 一个真正的新几内亚歌唱犬种。"

" It does." and the way of thinking about this quantitatively is that if it doesn't make a difference, the true population means of the groups will be the same.

“是的。 ”从数量上考虑这个问题的方法是， 如果它没有影响， 那么各组的真实人口均值将是相同的。

But if I knew the true population means-- So my question is: Is the mean of the population of people taking Food 1 equal to the mean of Food 2?

但如果我知道真实的人口均值—— 那么我的问题是：食用食物 1 的人口的均值是否等于食品 2 的均值？

The true population mean of the group that took food 1 will be the same as the group that took food 2, which will be the same as the group that took food 3.

吃食物 1 的组的真实总体均值将与吃食物 2 的组相同，这将与吃食物 3 的组相同。

Or another way you could say that, is that the difference P1 minus P2, the true proportion of men voting for the candidate minus the true population proportion of women voting for the candidate is going to be 0.

或者换一种说法，P1 减去 P2 的差值， 投票给候选人的男性的真实比例减去投票给候选人的女性的真实人口比例将为 0。
