The random sample above depicts a lower listing price and square footage versus what the national market shows. The lower than national square footage of properties on the average listing prices could also influence the way properties are sold. Whereas there is an association between x and y in this random sample. Therefore, as the square footage of the properties increases, the prices will also increase on the properties. I used the formula =rand () to get the random sample of 30 to provide a proficient and unbiased sample data as possible.
