Find the rejection region for each hypothesis test based on the information given. Sketch the sampling distribution. (3 points each)
1. : μ=121
:μ >121 α=0.01
n=39
σ=known
2. : μ=98.6
:μ ≠98.6 α=0.05
n= 25
σ=unknown
3. : μ=27
: μ <27
α=0.05
n=12
σ=known
4. : μ=65
: μ≠65
α=0.05
n=9
σ=unknown
5. : μ=2.9
: μ>2.9
α=0.01
n=50
σ=known
