What you need to do
你需要做什么
You are required to take a random sample of 100 transactions and conduct your analysis on the basis of this sample. DO NOT JUST TAKE THE FIRST 100
OBSERVATIONS IN THE DATABASE!
需要你采取100个交易随机样品，并在这个样品的基础上进行分析。不要只采取数据库的第100个观察！
Because your analysis is done on a RANDOM sample, your results will not be the same as the results of any other student group. Using statistical methods
listed below and any other techniques you think may be useful, summarise the data and comment on your findings.
因为您的分析是采用随机抽样，结果将作为其他学生组的结果是不一样的。下面列出了使用的统计方法和任何其他技术，你认为可能是有用的，汇总数据，并评论你的发现。

准备一个表的汇总统计数据（即平均，中位数，标准偏差，样本方差的人口和95％的总体平均数置信区间）。
(iii) Determine if there is a statistical difference between Loyalty and Regular customers. Make sure that you explicitly state your both null and
alternative hypothesis for each analysis.
