✔ 最佳答案
1-tail /2-tail is related to Ha.Ho usually is " = "
When Ha is " not = " , we use 2-tail.
When Ha is " >" we use 1-tail.
Whaen Ha is " < ", we also use 1-tail.
參考: my tutor taught this.

It relates to the setting of Ha.
If Ha <> (NOT EQIUAL) 50 (say), then it is two tailed test.
If Ha > / < 50 (say), then it is one tailed test.
You may ask when do we set the above hypothesis, then you should refer to the question.
