One is that a normal distribution falls off according to the negative exponential of the square of the distance from the mean.

一个是正态分布下降是依据中间部分转角处到平面距离的负指数。

To find the sampling distribution of the Chi Square statistic, simply take the outcome of each experiment and compute a Chi Square statistic for that result.

为了找到X平方分布统计的抽样分布，只需获取每次实验的结果，并且计算该结果的x平方分布统计。

Finally, I demonstrated how to simulate the Chi Square sampling distribution for different degrees of freedom, going beyond simply commenting on its derivation.

最后，我演示了如何模拟不同自由度的x平方分布的抽样分布，而不只是仅说明其来源。

Beginning in 1992 Lowe's started building massive 1-million-square-foot distribution centers to regulate the flow of goods to stores.

Home Depot, IKEA, Target and Wal-Mart all have distribution centres of more than 1m square feet (100, 000 square metres) in the Savannah area to handle cargo coming through the port, which sits at a nexus of interstate highways and railway lines that provide quick access to the south-east and Midwest.

Dell now owns 12 manufacturing and distribution centers, including 5 million-square-feet of space and 850, 000 square-feet of leased space, according to its latest annual report.
