[問題] 假設檢定的設定
這題是我在寫中央考古題看到的，
A local eat-in pizza retaurant want to investigatethe possibility
of starting to deliver pizzas. the owner of the store has determined
that home delivery willbe sucessful if the averag time spent on the
deliveries does not exceed 26 minutes. The owner has randomly selected
17 customers and has deliver pizzas to their homes.Whatare the hypotheses
the owner should test to show that pizza delivery will not be sucessful?
（1）H0：u＝26 （2）H0：u＝26 （3）H0：u＜26 （4）H0：u＝26
H1：u＞26 H1：u≠26 H1：u＝26 H1：u＜26
我在寫的時候，因為它最後一句說的是要檢驗它是不成功的
所以我選的是1，因為只要可以拒絕掉H0，也就是u會大於26
也就是不成功的，但是我看高點的統計詳解，寫的是第4個答案
到底哪一個才是正確答案呢？
