Project #1593 - Statistics

Hello, I am currently working on a study guide for an exam and cannot find the answers for these questions in the book that my class is using.

 

Please answer the questions as thuroughly as you can...

 

1. Explain the Frequentist interpretation of the confidence level?

 

2. Explain what is meant by the least squares regression line. Does the least squares line

always represent a statistically significant relationship between the two variables?

 

3. Discuss the similarities and differences between the z-distribution and the

t-distribution.

 

4. What are two commonly used distributions for p  ˆ . What are these distributions?

What are the similarities and differences between these two distributions? Discuss why 

one of these distributions gives the exact probability values and the other is used to 

approximate probability values.
