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.

The Margin of Error for μ 

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 ?

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

.

The best estimate for Female Satisfaction is

Focus on this model 

r² was computed and found to be 0.36.

If you categorize GPA into 3 different levels and run an ANOVA to test Ho: μ_LowGPA= μ_MedGPA= μ_HighGPA where μ stands for Satisfaction mean value, what are your expectations for the p-value ?

Still about this model 

This model was also considered to investigate if Surfers level of Satisfaction is different than non Surfers':

.

r² was computed and Ho: R²=0 was tested with a p-value=0.10.

The F test statistic value is
