Answer:
A Parameter
Step-by-step explanation:
It is important to first note that the word 'Paremeter" is contextual and it is being used in relations to Statistics and not any other course.
A parameter in statistics is a definite value that represents an entire population. In this question, the homes in the city of Utah in 2011 is the population and the number 230,000 is an average figure representing how much a home cost at that time in that city.
While homes can go as high as 250,000 or as low as 210,000, a statistical average cost of the homes in Utah in July 2011 was 230,000.
A parameter is crucial in understanding certain aspects of a particular population or system at a specific period in time, a parameter also does not change because every part of the population was sampled to come up with it. A parameter is accurate.
