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
x
the appraisal value of each apartment in the sample by appraiser B. The measurements

provide enough evidence to conclude that the mean estimation of the appraisal values of apartments by
