This model was considered to investigate if the level of Satisfaction is Gender dependent:

.

The best estimate for Female Satisfaction is

Consider this model

estimated with a different sample than the original, using α=0.10.

What is the best Satisfaction estimate, for a student with GPA=2.0 ?

A smaller sample was considered and we ran this

Based on the information given above, with α=0.05, what would your main conclusion be ?

The original sample (described in the beginning of the Exam)  was split among the Female categories and these descriptives computed:

and an ANOVA was run to find out if Satisfaction is Gender dependent.

Ho is

We want to investigate if Satisfaction is GPA dependent, BUT we want to do it using a Contingency Analysis (categorizing the variables)!

What is your expectation for Q if you consider a common α?

Run an ANOVA to find out if Satisfaction is Surfer dependent. 

What are your findings (using α=0.10) ?

Do you think Satisfaction is Gender dependent (use α=0.01)?

Focus on Satisfaction and these H0: μ ≤ 5 vs H1: μ >5.

What are your findings ?

Focus on GPA and consider α=0.10.
