2. the difference in the appraisal value of each apartment estimated by the two appraisers.
3. the actual sale value of each apartment in the sample.

Transcribed Image Text:Many times property value appraisers estimate the value of specific properties with minor or sometimes
major difference. A company that builds apartment buildings in Athens considers two appraisers, A and B.
who give an estimate of the sale price of their apartments. The sales department of the company has observed
that in most cases appraiser A gives smaller value estimates of their apartments. The company would like to
know if this is true for estimated values of apartments of other companies. Let X₁ be the appraisal value of
an apartment of other companies by appraiser A. Let X2 be the appraisal value of an apartment of other
companies by appraiser B. Also, let D=X₂-X₁. The company selected a random sample of apartments of
other companies. Let be the appraisal value of each apartment in the sample by appraiser A. Let *2 be
the appraisal value of each apartment in the sample by appraiser B. The measurements and *2 are in
thousands of euros and are given below. Let d=x₂-x. At the 5% level of significance, do these data
provide enough evidence to conclude that the mean estimation of the appraisal values of apartments by
appraiser A is smaller than the mean estimation of the appraisal values of apartments by appraiser B?
