Step-by-step explanation:
In statistics, Bias can be described as a term which depicts error if a sample is not taken evenly or it depicts errors taken from an unjust sampling.
In statistics, sampling bias means the errors which occur if one part of the population is favoured more then the rest of the populations. In this kind of bias, the individuals for experimentation are not chosen randomly.
As the customer satisfaction survey was distributed in only one of the gates hence, it does not give a generalized result and the result is biased.
Area is the length times the width.
When you know the area and one of the dimensions, divide the area by the known dimension to find the other one.
133 / 11 = 12.09
The room needs to be at least 12.09 feet wide. ( round answer if needed).
