Question: A real estate agent has received data on 150 houses that were recently sold in a suburban community. Included in this data set are observations for each of the following variables: the appraised value of each house [in thousands of dollars], the selling price of each house [in thousands of dollars], the size of each house [in hundreds of square feet], & the number of bedrooms in each house. Assume that this real estate agent wishes to examine a representative subject of these 150 houses. Use Excel to assist her by finding a simple random sample of size 10 from this frame.
