想請問一下這題怎麼寫？ 感謝各位大神🥺

2. The following table summarizes results from an experiment in which subjects were first classified as smokers or nonsmokers. After these subjects were given a treatment, later they were again classified as smokers or nonsmokers. After-smoker After- non-smoker Before- smoker 40 14 Before- non- smoker 5 80 2-1. How many subjects changed their smoking status after the treatment? 2-2. How many subjects appear to be unaffected by the treatment? 2-3. Using the appropriate frequencies, find the value of the test statistic. 2-4. Using a 0.025 significance level, find the critical value, and make your conclusion. 2-5. Based on the preceding results, do you think this treatment is really benefit to help people quit smoking?

（大一微積分） 請問這題這樣寫正確嗎？背流程寫的😅，圖一為需用到的定義 正確的話，想問紅色圈圈的1是怎麼來的？

DEFINITION Let f be a function defined on some open interval that con- tains the number a, except possibly at a itself. Then we say that the limit of f(x) as x approaches a is L, and we write lim f(x) = L x→a if for every number &> 0 there is a corresponding number 8 >0 such that | ƒ(x) − L| < ɛ if 0 < x-a <8 then

朋友，想問一下你的數學導論筆記本是用那一本書的呢？至少可以了解多一點點，來自清華大學的同學，謝

我想請問 原本fn只在所有compacts上一致收斂 D裡面會不會也包含沒辦法closed and bounded的部分 但我最後要證明的卻是在整個D上f都連續 這樣①③的選擇會不會只證明f在D中的任何compacts連續呢 如果會的話要怎麼改善證明 （高微證明小白求解..
