# Question

Determine the critical region and the critical values used to test the following null hypotheses:

a. Ho: µ = 55 ( ≥), Ha: µ < 55, a = 0.02

b. Ho: m__86 ( ≥), Ha: µ < 86, a = 0.01

c. Ho: µ = 107, Ha: µ = 107, a = 0.05

d. Ho: µ = 17.4 (≤), Ha: µ > 17.4, a = 0.10

a. Ho: µ = 55 ( ≥), Ha: µ < 55, a = 0.02

b. Ho: m__86 ( ≥), Ha: µ < 86, a = 0.01

c. Ho: µ = 107, Ha: µ = 107, a = 0.05

d. Ho: µ = 17.4 (≤), Ha: µ > 17.4, a = 0.10
