A growth hormone was given in three different doses to two types of animals. A two-way ANOVA procedure was conducted that evaluated the change in growth rates across the various dosage/type combinations. What is the appropriate conclusion based on the output shown here? (Useα= 0.05.)
Since interaction is present, there is some problem with determining whether dosage affects growth rate.
Although interaction is present, we can still determine that the different types of chimpanzees have differing growth rates becauseH0is not rejected for the type factor.
It appears that dosage does have some effect on the growth rates of the animals.
Since interaction is not present, we can safely say that the relationship between dosage and growth rate is different for the different types of animals.
