Question 8 of 8

Calculate the margin of error and construct the confidence interval for the population mean (you may assume the population data is normally distributed):

Standard Normal Distribution Table

a. x̄ =6.138,n=316, σ =0.941, α =0.05 x̄ =6.138,n=316, σ =0.941, α =0.05

E=E=  

Round to 3 significant digits

< μ <  < μ <

Round to 3 decimal places

b. x̄ =17.63,n=625, σ =3.44, α =0.01 x̄ =17.63,n=625, σ =3.44, α =0.01

E=E=  

Round to 3 significant digits

< μ <  < μ <

Round to 2 decimal places
