....
(Choose all statements that are correct)
The experimental results are considered to be statistically significantly

Correct!

expected results are so large (statistically) that we should rule out the
hypothesis that generated those expectations
Correct!
Correct!
The difference between the experimental results (data) and the
expected results are NOT that great (in a statistical sense). Thus, we
