1. A realtor wants to examine the relationship between the assessed value of a property (land and buildings) and the size of any house located on the property (measured in square feet). Below is a random sample of 6 properties in a subdivision that was built 5 years ago:

Square Footage (in 100's) 21.7 22.5 23.0 23.0 26.5 29.0 Assessed Value (in $1,000's) 1,090 1,150 1,180 1,195 1,240 1,276
