Question

is this true or false
many trials are not needed before a hypothesis can be accepted as true

Answer 1

Ummm... this is a statistics or psychology or something like that question. The area you are in is for Computer Science.

Answer 2

Yes a hypothesis cannot be accepted as true untill all possible scenarios are tested. For a logic to be true a small change in the input can cause the output to change. This is to be tested before the statement is made radical or termed to be true in its output.
