Sandra earns $22,000 per year. Her earnings put her in the 20% tax rate. What is her tax owed? We can easily rephrase the question: what is 20% of 22000? 20% is actually one firth, so we can divide 22000 by 5. First, 20 000 by 5 is 4000 and 2000 by 5 is 400. We sum it up: 4000+400=4400, and that's the correct answer!

C. Correlated assignment
In research, the term random assignment refers to the use of chance procedures to make sure that each participant of the study is assigned to a random group. In other words, participants are assigned to random groups.
In this example, Frances wants to study the effects of violent videogames on children's levels of aggression. As children come to the lab, she flips a coin and if it's heads they play a video game. If it's tails, they play a non-violent video game. We can see that <u>Frances is using a random method to assign the children to the groups (flipping a coin) and therefore they are assigned to random groups because she is using a chance procedure.</u> Therefore she is using random assignment technique

Katherine's opportunity cost of attending the lecture is: the transportation and time cost of getting to the lecture event itself plus the reduction in her physics exam grade by not studying tonight.

Maturation is a threat to internal validity stemming from either long-term or short-term physiological changes occurring within the participants that may influence the dependent variable.
<h3>
What are physiological changes?</h3>
Ageing causes physiological changes in all organ systems. Arteriosclerosis develops, blood pressure rises, and cardiac output declines. Lung function is compromised, vital capacity is reduced, and expiratory flow rates are slowed.
Pregnancy causes a number of physiological changes in the mother, such as an increase in fat and total body water, a drop in plasma protein concentrations, particularly albumin, an increase in blood volume, cardiac output, and blood flow to the kidneys, and a decrease in blood pressure.
