The experimental units are what you apply the treatments to. In this experiment it would be the subjects or the customers in this situation since they will be treatment (either standing at their regular height or squatting to meet the eye level which could affect the amount of tip they give). An example of randomization can be numbering each table in the restaurant and picking them out of a hat and going to that table that you randomly chose and imposing the treatment on the customers there. Because tips depend on the income of the customers and how much they are willing to give for their meal. If not even income some people are willing to give despite how much money they make so their tips may higher than the wealthy crowd. Other factors the experimenters may not be able to control is the mood of the customers as well isn't it more likely if someone is enjoying their time to give more to the server despite the service the waiter.

The best thing that we process the verbal information is by the use of semantic encoding according to Craik and Tulving. Semantic Encoding is defined as the encoding and processing of sensory input that has a particular meaning or can be applied to a context.

Answer:
50% of the hatched chickens would be speckled, 25% would be black and 25% would be 25%
Explanation:
The black chickens are the dominant allele and the white chicken are the recessive allele. Since the black chicken is dominant, Let the genotype of the black chickens be (BB) and the genotype of the white chicken be (ww).
If the Black and white chicken are cross bred and the eggs hatched are black with white speckles, i.e (Bw). The genotype of all the hatched chickens would be (Bw). Where Bw is speckled chicken.
If the hatched chicken with genotype (Bw) are interbred, the resulting hatched chickens genotype would be BB, Bw, Bw and ww for four offsprings. This shows that 50% of the hatched chickens would be speckled, 25% would be black and 25% would be 25%
