Question: Use the t-Table for reference. Calculate a 95% Confidence interval for the following samples: x = 450, n=200, =100 x = 105, n=50, =15 x

Use the t-Table for reference.

  • Calculate a 95% Confidence interval for the following samples:

x = 450, n=200, =100

x = 105, n=50, =15

x =19, n= 17, s = 5

x = 8, n = 40, s = 1.6

x = 8.35, n =30, s =1.59

  • Calculate a 99% Confidence interval for the following samples:

x = 525, n=110, =100

x = 305, n=85, =50

x =19, n= 17, s = 5

x = 15, n = 60, s = 2.25

x = 25.43, n = 50, s = 5.15
