跪求作业（附件）里Part A 第二题和Part B 第三第四第五题 里的R code，作业还有11个小时就要交。作业分值很大，自己的R水平实在有限。如果有哪位老师能帮忙，不胜感激。如果没全做完，做多少都行。谢谢各位了。

方便大家看，把题贴上来 ：题一
Assuming the number of telephone calls made by the salesperson before a successful sales call
may be modelled by the geometric distribution, give a Monte Carlo algorithm for simulating
this random variable, using p=0.21.
Implement this algorithm in R and simulate 5 data sets of size 100. Present your results in
a frequency table with one row (or column) for each simulated data set.

题二：
Extend your computer programme so that it computes the test statistic X平方 for each simulated
sample. Run this programme 1000 times to obtain a (parametric) bootstrap distribution of
X平方 that represents the distribution of the test statistic under the null hypothesis. Plot the
histogram and nd the 5% critical value.

题三：Compare the bootstrap distribution of the test statistic with the theoretical distribution.
What is your test decision if you use the critical value from the simulation?

作业交了么？300论坛币还有效么？

还有2个小时交有效阿，您会做么？
