原本只是想統計我上一篇文章底下的推文
應該是語意模糊，看起來像是我要統計這次打貓貓人數 ~"~
也沒差，我就把數據加進去
現在的結果是 Extra:85/166 高級:70/547 中級:9/251 (初級n*p太低還是不考慮)
P(extra)的95% C.I.= (0.436,0.588)
P(高級) 的95% C.I.= (0.100,0.156)
P(中級) 的95% C.I.= (0.0129,0.0591)
(小聲說昨天算的數字有些問題，現在改了 XD)
EXTRA 貌似約五成唷，高級也比一成高，中級連高級一半都不到 科科
-----------------------------------------------------------
來騙個P幣
由於我念的是統計
統計底下推文數據供大家作參考
Extra:37/85 高級:22/218 中級:5/80 初級:1/1
(初級這.....我就不多說了，只能說您人品真好)
假設母體分配服從Ber(p)，採常態分配估計信賴區間，取α=0.05
理論式子部份我也不提哩，直接丟結果
P(extra)的95% C.I. =(0.329, 0.541)
P(高級) 的95% C.I. =(0.061, 0.141)
P(中級) 的95% C.I. =(0.0091, 0.1159)
結論就是那三個level貓貓掉卡率有很大的機率會落在這個範圍
可看出就算是extra也極可能不到5成
高級大概1成，中級大概高級的一半，大家加油
