You can put this solution on YOUR website! What critical region(s) for z would be used to test the hypotheses:
H0:µ = 10
Ha:µ ≠ 10,
for α = 0.05 ?
-----
Ha determines that this is a 2-tail test.
-----
There are two tails. Left tail with area = 0.025. Right tail with area 0.025
------
Critical regions.
z < -1.96 for the left tail
z > +1.96 for the right tail
