Question
First National Bank employs three real estate appraisers whose job is to establish a property's market value before the bank offers a
mortgage to a prospective buyer. It is imperative that each appraiser values a property with no bias. Suppose First National Bank
wishes to check the consistency of the recent values that its appraisers have established. The bank asked the three appraisers to
value (in $1,000s) three different types of homes: a cape, a colonial, and a ranch. The results are shown in the accompanying table.
