題目是英文的，不好意思 Six infants were involved in a study to compare the effectiveness of two medications for the treatment of diaper rash. For each baby, two areas of approximately the same size and rash severity were selected, and one area was treated with medication A and the other with B. The number of hours for the rash to disappear was recorded for each medication and each medication and each infant, and the values obtained are given below. Infant 1 2 3 4 5 6 Medication A 46 50 46 51 43 45 Medication B 43 49 48 47 40 40 At the significance level 0.01, is there sufficient evidence to conclude that a difference exists in the mean time required for the elimination of rash? 以上就是題目大意是說有六個嬰兒得了疹子有A 和B 兩種藥來治療每個嬰兒身上有兩片大小嚴重情況相當的疹子分別使用A 和 B兩種藥來治療題目大意就是這樣我是統計初學者而且學得滿糟糕的我不太清楚這個題目是要用t來算還是用z 麻煩各位高手幫忙解答感激不盡呀~~~~ -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 61.230.25.236
