Question:

Provide the rejection region based on a t- test statistic for the following situations:
a. H0: μ ≥ 28 versus Hα: μ < 28 with n = 11, α = .05
b. H0: μ ≤ 28 versus Hα: μ > 28 with n = 21, α = .025
c. H0: μ ≥ 28 versus Hα: μ < 28 with n = 8, α = .001
d. H0: μ = 28 versus Hα: μ ≠ 28 with n = 13, α = .01
