G. The experimental units are diets A and B
Answer:
A. This is an example of a block design.
D. The treatments are diets A and B.
F. The experimental units are the 20 rabbits.
Explanation:
The randomized block designs are used in experiment when there is only one variable of prime importance but along with it there are several nuisance factors. As in this case, the prime variable is the impact on weight of rabbits when they consume one the given diets. However, several nuisance factors are unequal weights of the rabbit, different class of rabbits, eating habits of rabbit, time of feeding etc.
Treatment in an experiment is the independent variable that is varied to measure its impact on the subjects of the experiment.
Here these independent variables are diet type A and B and the subject is the group of 20 rabbits. Subjects are also referred as experimental unit i.e on which the experiment is being conducted
Hence, option A, D and F are correct
They decrease blood flow.
They increase hydration levels.
They decrease hydration levels.
