For each of the following hypothesis tests concerning the population mean, , state the rejection point condition

Question:

For each of the following hypothesis tests concerning the population mean, μ, state the rejection point condition or conditions for the test statistic (e.g., z > 1.25); n denotes sample size.
A. H0: μ = 10 versus Ha: μ ≠ 10, using a z-test with n = 50 and α = 0.01
B. H0: μ = 10 versus Ha: μ ≠ 10, using a z-test with n = 50 and α = 0.05
C. H0: μ = 10 versus Ha: μ ≠ 10, using a z-test with n = 50 and α = 0.10
D. H0: μ ≤ 10 versus Ha: μ > 10, using a z-test with n = 50 and α = 0.05
