Regression to the mean and selection bias are the superfluous variables that are removed by randomly choosing schools for the experiment and control groups.
A statistical phenomenon known as regression to the mean (RTM) states that if a random outcome of any measurement or event is severe in the first example, the second or following outcomes will be less extreme. In other words, it will be somewhat near to the distribution's mean or center.
According to regression to the mean (RTM), if an experiment's first result is extreme, the second result will be more in line with the population mean.
Decisions are made incorrectly as a result of this prejudice.
To mitigate the detrimental impacts of regression to the mean, organizations can exercise critical thinking and undertake a randomized controlled trial (RCT) with an experimental group and a control group.

Answer:
The situation that represents this situation is:
Step-by-step explanation:
The amount of time t needed to assemble the set is inversely proportional to the number people n working.
This means that:
In which k is the constant of proportionality.
Twelve people can assemble the set in 5 hours.
This means that for 
. We use this to find k.
Write an equation to represent the situation.
