  1. Use tables in the Appendix to specify the appropriate Rejection Region ONLY for each hypothesis test described below.
  • H0: σ2 = 25               (With a sample size n = 20.)

Ha: σ2 < 25

α = .10

(b) H0: μ = 80                (With σ unknown and a sample size n = 36.)

Ha: μ > 80   

α = .05

(c) H0: p1 – p2 = 0 (With sample sizes n1 = n2 = 60.)

Ha: p1 – p2 ¹ 0

α = .01
