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

Consider the previous ANOVA (Question 9), that was run with factors Female and Surfer.

A new factor, with a sum of squares equal to 40 and 4 different categories, was added.

What is the F test statistic value for Female ?

The previous ANOVA (described in Question 7) was re run using both factors: Female and Surfer.

How many degrees of freedom were assigned to the Residuals sum of squares ?

Can you compute a Margin of Error for Satisfaction μ ?

About GPA μ... with H1: μ<k.

Using the reported information regarding the original sample (n=35), to get a p-value=0.0548, k is approx.

About Satisfaction, a reduced sample (n=15) was used to test Ho: μ=5 vs H1: μ≠5, with α=0.05.

The estimates for μ and σ, computed with this smaller sample, were exactly the same: 5.13 and 2.13.

We

Focus on Surfer and use the sample to test Ho: π≥0.5 vs H1: π<0.5
