- Calculate a 95% Confidence Interval for the following samples:=450, N=200, σ=100=105, N=50, σ=15= 19, N = 17, s = 5= 8, N = 40, s = 1.6= 8.35, N = 30, s = 1.59
- Calculate a 99% Confidence Interval for the following samples:=525, N=110, σ=100=305, N=85, σ=50= 19, N = 17, s = 5= 15, N = 60, s = 2.25= 25.43, N = 50, s = 5.15
