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 究竟是我寫錯,還是他寫錯? 想說PO上來問一下大家,麻煩了。 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.122.168.207
