不论你签了多少份保单,均值永远是0.2,所以这就是一个关于x=0.2对称的,正态分布
Well, the mean is always .2 no matter how many policies you write, so it's going to be--we're going to have a normal distribution centered on .2.
可能是正态分布，也就是高斯分布，只要有平均值和标准偏差值，你就可以进行调用，大部分的值都是集中在平均值附近的。
It could be normal, everything, that would be a Gaussian, where if you recall there was a mean, and a standard deviation, and most values were going to be close to the mean.
正态分布数据认为，样本中约68%的数值分布在距离平均值为1的标准偏差之内。
Normally distributed data assumes that about 68% of the values in the sample are within 1 standard deviation of the mean.
您已经看到均值和标准偏差，直观上您可能会觉得温度是正态分布的。
You have seen the mean and standard deviation, and intuitively you might expect temperatures to be distributed normally. Let's check

分析和实际模拟表明，在以正态分布进行抽样的前提下，合理选取抽样样本平均值和标准差，可使抽样效率进一步提高。
Theorical analysis and practical simulation indicate that if the samples are of normal distribution, the modelling efficiency can be increased further by using sensible parameters.
特别地，本文集中讨论当数据是来自参数未知的正态分布四舍五入后的数据，均值和方差的联合置信集。
In particular, we focus discussion on joint confidence sets of the parameter mean and variance when a rounded sample comes from the normal distribution with both parameters unknown.
