If you use a 0.05 level of significance in a two-tail hypothesis test, what decision will you make if ZSTAT=+1.55?
To find the , A z-score table is used.
This Z table below shows area to the left of A Z-value (Total area is 1)
we know that area to the right of is 0.025.
This means that area to the left of should be 1-0.025 = 0.975
We look for 0.975 in the table and find our concerned Z value which is 1.96
