（I）求X的分布列和数学期望 $E\left(X\right)$ ；

（II）已知王老师在2017年6月的所有工作日（按22个工作日计）中共花费交通费用110元，请判断王老师6月份的出行规律是否发生明显变化，并依据以下原则说明理由．

原则：设 $a$ 表示王老师某月每个工作日出行的平均费用，若 $\left|a-E\left(X\right)\right|\ge \sqrt{\frac{D\left(X\right)}{5}}$ ，则有95％的把握认为王老师该月的出行规律与前几个月的出行规律相比有明显变化．（注： $D\left(X\right)=\sum _{i=1}^n{\left(x_i-E\left(X\right)\right)}^2{p}_i$ ）

增加：在缺词处加一个漏字符号（∧），并在其下面写出该加的词。

删除：把多余的词用斜线（\）划掉。

修改：在错的词下划一横线，并在该词下面写出修改后的词。

注意：1）每处错误及其修改仅限一词；

2）只允许修改10处，多者（从第11处起）不计分。

    My name is Li Hai. I come from an island to the south of China called Hainan Island. There is a good number of animals living on or around the island. We have monkey, deer, birds or varieties of fish. Hainan Island is a place to know about fish. My father is a fisherman with which I have been on many fishing trips.
