Re: [抽卡] 我終於抽到阿提了…的統計結果
假設檢定姍姍來遲了
不好意思我用有母數因為無母數我不知道要用哪個Test
(後天還要考試希望知道的大大指點一下...)
設P=抽到暗屬性封印卡的機率,在0.95的信心水準下
檢定抽到暗屬性封印卡的機率有沒有大於200%
H0:P<=0.3333(1/3)
H1:P>0.3333(1/3)
N=100 P hat=0.34
alpha=0.05
Reject Region C={Z|Z>1.645}
Z=0.34-0.3333/(0.3*0.7/100)^1/2=1.43791 不落入拒絕域
不拒絕H0,亦即無充分證據顯示抽到暗屬性封印卡機率提升超過200%
