二、分別蒐集五個地點四個時段的空氣品質監測值，地點 A 為 113，地點 B為 75，地點 C 為 90，地點 D 為 93，地點 E為 103。若四個時段的數據中，前兩個時段為日間的數據，後兩個時段為夜間的數據，假設前述資料符合變異數分析的各項假設， ＝0.05。請檢定五個地點及日夜間的空氣品質監測值是否有差異。（25 分）注意：F4,14,0.05＝3.11，F5,14,0.05＝2.96，F4,19,0.05＝2.90，F5,19,0.05＝2.74，F4,1,0.05＝225，F2,14,0.05＝3.74，F1,14,0.05＝4.60，F1,4,0.05＝7.71，F1,19,0.05＝4.38，F2,19,0.05＝3.52，t0.05,14＝1.76，t0.05,4＝2.13，t0.05,1＝6.31，t0.05,19＝1.73
