【题文】某苗圃用两种不同的方法培育了一批珍贵树苗,在树苗3个月大的时候,随机抽取甲、乙两种方式培育的树苗各20株,测量其高度,得到的茎叶图如图(单位:cm):
![](http://static.zujuan.xkw.com/Upload/2016-08/04/04a20811-60aa-40b3-b52e-1d196752d2b9/paper.files/image213.jpg)
(Ⅰ)依茎叶图判断用哪种方法培育的树苗的平均高度大?
(Ⅱ)现从用甲种方式培育的高度不低于80 cm的树苗中随机抽取两株,求高度为87 cm的树苗至少有一株被抽中的概率;
(Ⅲ)如果规定高度不低于85cm的为生长优秀,请填写下面的2×2列联表,并判断“能否在犯错误的概率不超过0.025的前提下认为树苗高度与培育方式有关?”
