confidence intervals and precision|The One-Mean z-Interval Procedure|When to Use the One-Mean z-Interval Procedure

Confidence Intervals for One Population Mean When σ Is Known Obtaining Confidence Intervals for a Population Mean When σ Is Known The z-interval procedure works reasonably well even when the variable is not normally distributed and the sample size is…

Understanding Binomial Confidence Intervals 二项分布的置信区间

Source: Sigma Zone, by Philip Mayfield The Binomial Distribution is commonly used in statistics in a variety of applications. Binomial data and statistics are presented to us daily. For example, in the election of political officials we may be asked…

18年春招某编程题：有三个整数X,Y,Z,要求进行若干次操作使得X,Y,Z相等

题目描述: 给定三个整数X,Y,Z,要求进行若干次操作使得X,Y,Z相等,操作有两种: 1.从X,Y,Z中选择两个数都加1. 2.从X,Y,Z中选择一个数加2. 求最少需要多少次操作. 题目思路: 1.对X,Y,Z三个数进行排序,此处用的是降序排序.假设排序完之后X>Y>Z,如果Y-Z是奇数的话,那么对Z进行(Y - Z)/2次操作2的话,Z就会变成了Y-1了,即此时的Y=Y,Z=Y-1.那么此时只需先对Y,Z进行X-Y次操作1,使得X=X,Y=X,Z=X-1.然后再对X,Y进行1次操作1,最…

ArcGIS高程Z值的去除方法

在ArcGIS中,我们常用的几何类型有点.线.面.体(体,在涉及三维的情况下使用),但在这之外,可能会遇到带ZM的类型,如图所示,面ZM,它与面类似,但比面多两个字段. 在编辑中查看草图属性可看到Z值和M值.Z值是用来存储高程属性信息的,M值是用来存储其他属性信息的,如温度.浓度等.这里的数据是CAD文件转过来的,所有有高程值,但没有M值. 从下面的WKT格式中可以看出几何点可能的类型有Point.PointZ.PointM.PointZM四种格式,Polyline.Polygon也是类似的.…

贪心：zoj3953 Intervals

Description Chiaki has n intervals and the i-th of them is [li, ri]. She wants to delete some intervals so that there does not exist three intervals a, b and c such that a intersects with b, b intersects with c and c intersects with a. Chiaki is inte…

[LeetCode] Data Stream as Disjoint Intervals 分离区间的数据流

Given a data stream input of non-negative integers a1, a2, ..., an, ..., summarize the numbers seen so far as a list of disjoint intervals. For example, suppose the integers from the data stream are 1, 3, 7, 2, 6, ..., then the summary will be: [1, 1…
