I want to know if there is a sample distribution of coefficient alpha or no?
What 's the hypotheses testing for coefficient alpha?
It is a mute point. You are not happy with an alpha significantly greater than zero. You want an alpha that is much higher, say greater than 0.80

Hi Mahmoud, to add to Ruth's reference list, you might find Jose Cortina's article about the meaning of alpha very helpful:
