1.  We have 15 Rats given 3 Cancer Treatments (placebo, chemo, radiation). We measure cancer growth in millimeters.

•Treatment 1 rats’ measures: 4,5,2,4,4

•Treatment 2 rats’ measures: 2,2,3,4,4

•Treatment 3 rats’ measures: 3,1,1,3,1

•Assume normal distribution.

•Are they different at the alpha = .05 level?

 

Conduct an ANOVA and post-hoc analysis if necessary.  Use alpha =.05 (standard).

Interpret all results.

Provide plots of effects.

 

2.  We have male and female patients in a specific clinic.  Satisfaction scores by gender follow.

 

Male:  70,60,80,50,30,50,70, 50

Female:  80,50,90,70,45,90,100

 

Are these scores statistically different at the .05 level?  Conduct the appropriate test.
