Question

I need help with part 3.

Choose the correct type of hypothesis test. Then find the critical values for a=0.10 and α = 0.05. Round your answers to three decimal places, if
necessary.
H₁
Critical Values for α=0.10
Critical Values for α =
= 0.05
Left-tailed
Right-tailed
Two-tailed
-1.645 and 1.645
-1.960 and 1.960
Part: 2/3
Part 3 of 3
Determine whether to reject Ho.
(b) Since the test statistic, z=2.65, is
level.
in the critical region, we reject
Ho at the a=0.10
(c) Since the test statistic, z=2.65, is
level.
in the critical region, we reject
0
Ho at the α = 0.05
