Solution

Make Decision
we do not reject Ho when value of | Zo | < | Z | and

it is said at Alpha = .05 do not reject Ho, it is true for each alpha exceed 0.05. Z table value always increases when Alpha gets bigger. As we don\'t reject Ho with alpha 0.05, higher the alpha always above to | Zo |

you may not reject it at alpha = .03 [ANSWER]
