8. Please graph a “Z” distribution along with two “T” distributions. Provide the degrees of freedom for each of the two “T” distributions. Hint: Too many “dfs” would make the “Ts” become “Z”.

Expert Solution

Above is the most accurate graph of standard normal (Z) distribution along with 4 T distribution. Dofs are 2-1= 1,

3-1=2, 6-1=5 , 30-1=29.

This figure shows Z distribution with 2 T distribution. Dofs are 5-1 =4 and 17-1 =16

Generally degree of freedom above 30 is considered as a threshold value. If DOF is more than 30 then It is very apprximated by normal distribution.

If you find my answer useful then please support me by putting thumbs-up. Thank you.

How does a t-distribution differ from the z-distribution? How do degrees of freedom (df) affect this? What is the effect of this difference on hypothesis testing? - Your friend performed a two-tailed experiment in which n = 20. He couldn’t find his t-table, but remembered the t-critical at df = 10. He decided to compare his t-obtained to this t-critical and determined the results were not significant. Is this ok? Why or why not.
