If a score or mean does not fall beyond the critical value m
If a score or mean does not fall beyond the critical value (meaning that it is neither more positive nor more negative, depending on your hypothesis) then we should:
a.) reject the null
b.) accept the null
c.) reject the alternate
d.) fail to reject the null
Solution
We reject if is falls beyond critical values, otherwise we fail to reject the null,
d.) fail to reject the null
Note that we did not accept null.
