Answer
α = 0.1, α/2=0.05, From the table, critical value = 1.645
Rejection region = z< -1.645 or z> 1.645
Non rejection region = [-1.645, 1.645]
b.α = 0.01, From the table, critical value = -2.326
Rejection region = z< -2.326
Non rejection region = z > -2.326
c.α = 0.05, From the table, critical value = 1.645
Rejection region = z> 1.645
Non rejection region = z <1.645
