Dr. Guy.
I just want to know before I take the quiz if these answers are correct. I want to make sure I do understand how to use the formula properly.

3.2 H(0)μ =42,500 AND H(1)= ≠ 42,500

4. H(0) μ =100
H(1) ≠ 100
α=0.1
z-critical = ± 2.58
z-obtained = 3.33
decision to reject H(0) and accept H(1)

5. H(0) μ = 21
H(1) = ≠ 21
α=0.5
z-critical = ± 1.96
z-obtained= -3.43
Decision to reject H(0) and accept H(1)


6 H(0)μ =13
H(1)= ≠ 13
α =0.05
z-critical = ± 1.96
z-obtained = 2.5
Decision to reject H(0) and accept H(1)

7 H(0) μ = 4
H(1) ≠ 4
α =0.01
z-critical = ± 2.58
z-obtained =1.304
Decision is do not reject H(0) and reject H(1)
