This assignment explores calculating confidence intervals based on given data.
-Step 1: Answer the following questions:
Use the t-Table for reference.
Calculate a 95% Confidence interval for the following samples:
x̄ = 450, n=200, ơ=100
x̄ = 105, n=50, ơ=15
x̄ =19, n= 17, s = 5
x̄ = 8, n = 40, s = 1.6
x̄ = 8.35, n =30, s =1.59
Calculate a 99% Confidence interval for the following samples:
x̄ = 525, n=110, ơ=100
x̄ = 305, n=85, ơ=50
x̄ =19, n= 17, s = 5
x̄ = 15, n = 60, s = 2.25
x̄ = 25.43, n = 50, s = 5.15
