a. Do these data indicate a significant difference between the treatments at the α = .05 level of significance?

b. Compute r2 to measure the size of the treatment effect.

 

c. How would the outcome of the hypothesis test and the measure of effect size ?

 

( I believe the S1= 1.6 and the S2= 2.89, but not sure I am even on the right track)
