4. 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  = 0.01 B. H0: μ = 10 versus Ha: μ ≠ 10, using a z-test with n = 50 and  = 0.05 C. H0: μ = 10 versus Ha: μ ≠ 10, using a z-test with n = 50 and  = 0.10 D. H0: μ  10 versus Ha: μ > 10, using a z-test with n = 50 and  = 0.05
