报章报道: 国家环境局发言人透露， 违例者均为初犯， 罚款额为200元， 重犯可罚高达1000元。 除此， 放置在及新增禁烟区内的垃圾桶将移走， 換成不设烟灰缸的桥‚ 垃圾捅。 读了这则新闻‚ 我不禁感到欣慰‚ 赞成违例者会被惩罚的行为‚ 相信新加坡公民也会点头咂嘴。 国家随着新加坡烟民逐年增加‚ 本地公共场所的禁烟范围正式扩大近三个月来， 共有超过500名烟客在新禁烟令下违例吸烟而遭罚款。 他们多数是在有盖走廊， 住宅区公共空间， 及有盖行人天桥等处被稽査人员逮个正着。 原因: • 环境局数据显示， 本地去年全年共有4050起烟客违例吸烟铵罚款案例 • 烟客喜欢聚集在有烟灰缸的垃圾桶抽烟，所以这些垃圾桶都被搬离到巴士站五公尺远的地方 • 当局希望通过店员和烟客的接触，把信息传达出去‚ 让禁烟信息在社区内的渗透度更广 • 让违例者遵守新禁烟令的条规 • 提高公众对新增禁烟区的认识， 环境局的义工至今已展开超过950次的社区巡逻， 向各个社区内桶的烟客和居民说明新禁烟条例 • 不要伤害到非吸烟者‚ 减少二手烟的问题 后果: • 我国约有36万烟民

English is spoken as a native language by about 375 million people and as a second language by around 375 million speakers in the world. And according to research by the British Council‚ speakers of English as a second language will soon outnumber those who speak it as a first language. Philippines‚ for example‚ is also using English as its second language‚ and every year the number of fluent English speakers here is getting bigger and bigger‚ which I think is very beneficial for our country.

Random number tables have been used in statistics for tasks such as selected random samples. This was much more effective than manually selecting the random samples (with dice‚ cards‚ etc.). Nowadays‚ tables of random numbers have been replaced by computational random number generators. Tables of random numbers have the desired properties no matter how chosen from the table: by row‚ column‚ diagonal or irregularly. The first such table was published by a student of Karl Pearson’s in 1927‚ and

WHAT IS A RANDOM VARIABLE? A random variable assigns a number to each outcome of a random circumstance‚ or‚ equivalently‚ a random variable assigns a number to each unit in a population. It is easier to create rules for broad classes of situations and then identify how a specific example fits into a class than it is to create rules for each specific example. We can employ this strategy quite effectively for working with a wide variety of situations Involving probability and random outcomes. We

Thiss thesis contains work on reinforced random walks‚ the reconstruction of random sceneriess observed along a random walk path‚ and the length of a longest increasing subsequencee in a random permutation. In this introduction‚ I will survey some of the work inn the area and describe my results. Furthermore I will explain how all three subjects fit intoo the framework of random walks in stochastic surroundings. Section 1 is dedicated to reinforcedd random walks. Section 2 describes scenery reconstruction

years drugs have been becoming more common when it comes to high schoolers. There has been a lot of controversy on whether or not random drug testing is a good or bad thing for athletes. Random drug testing is becoming more common to many schools throughout the world to help reduce substance drug abuse in athletes and to allow schools to help keep students safe. Random drug testing in high school athletes is a great way for adults to help kids overcome drug abuse. Drug testing in schools provides

Types of Sampling In applications: Probability Sampling: Simple Random Sampling‚ Stratified Random Sampling‚ Multi-Stage Sampling * What is each and how is it done? * How do we decide which to use? * How do we analyze the results differently depending on the type of sampling? Non-probability Sampling: Why don’t we use non-probability sampling schemes? Two reasons: * We can’t use the mathematics of probability to analyze the results. * In general‚ we can’t count on a non-probability

Stock Market Prices Do Not Follow Random Walks: Evidence from a Simple Specification Test Andrew W. Lo A. Craig MacKinlay University of Pennsylvania In this article we test the random walk hypothesis for weekly stock market returns by comparing variance estimators derived from data sampled at different frequencies. The random walk model is strongly rejected for the entire sample period (19621985) and for all subperiod for a variety of aggregate returns indexes and size-sorted portofolios. Although
