Activity (5 POINTS EACH)
Direction: Compute the test statistic given the following information and test the
hypotheses.

1. H0 : µ = 80 Ha : µ ≠ 80 �= 87; σ = 10; n = 35; α = 0.01
2. H0 : µ = 50 Ha : µ < 50 �= 40; σ = 12; n = 35; α = 0.05
3. H0 : µ = 60 Ha : µ ≠ 6 �= 77; σ = 10.5; n = 50; α = 0.1

4. H0 : µ = 30 Ha : µ > 30 �= 32; σ = 5.5; n = 35; α = 0.05
5. H0 : µ = 40 Ha : µ ≠ 40 �= 42; σ = 9; n = 32; α = 0.01
