FINA 6421: Homework 2Please submit onehomework answer set for your group, along with individualversions of your code for each member of the team. Groups are expected to work together, but all individuals are expected to maintain their own uniquecode base (code submissions mustbe different for each person in the team). The best way to learn the material is to think about how you want to structure your code together as a team, and then actually implement it yourself!Use the coinTosser() function discussed in class to build a function binomialTosser(n,p,k)that generates k realizations of a binomial random variable with parameters n and p.Recall that a binomial(n,p) random variable counts the number of heads flipped in n independent tries using a coin with a probability p of heads on any individual toss.If you need more of a primer on binomial random variables, please search the internet.a.Build the function and supply your code for it.b.What is the population mean of a binomial random variable? What is the population variance of a binomial random variable?c.Use the function to generate 100000 binomial(10, 0.25) random variables. Plot an expanding window mean estimate from your 100000 random variables as a function of sample size. (An expanding window mean computes, for each value between 1 and 100000, the sample mean of all random variables up to and including that value. So the first entry is the “mean” of the first value, the 2ndentry is the mean of the first two entries, the 3rduses the first 3 data points, … , the 100000thentry uses all 100000 data points.)d.Find the (approximate) sampling distribution of the sample mean of a binomial random variable given the known variance of the binomial (ie, use the known population variance in place of ). What is the probability based on the approximate sampling distribution that the mean is more than 0.01 from the population mean you found in part b if your sample size isi.k = 100ii.k = 1000iii.k = 10000iv.k = 100000代写CS Finance|建模|代码|系统|报告|考试编程类：C代写,JAVA代写,数据库代写,WEB代写,Python代写,Matlab代写,GO语言,R代写金融类：统计，计量，风险投资，金融工程，R语言，Python语言，Matlab，建立模型，数据分析，数据处理服务类：Lab/Assignment/Project/Course/Qzui/Midterm/Final/Exam/Test帮助代写代考辅导天才写手,代写CS,代写finance,代写statistics,考试助攻E-mail:[email protected]微信：BadGeniuscs 工作时间：无休息工作日-早上8点到凌晨3点如果您用的手机请先保存二维码到手机里面，识别图中二维码。如果用电脑，直接掏出手机果断扫描。
