Use the t-Table "The t-Table" for reference.

- 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

**Step 2** Save and submit your assignment.

Please create a **narrative explanation** of the calculations where you describe, step-by-step, how you arrived with the solution to these questions.

When you have completed the assignment, save a copy for yourself in an easily accessible place and submit a copy to your instructor using the dropbox.
