Exercise 2 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 be the appraisal value of an apartment of other companies by appraiser A. Let *, be the appraisal value of an apartment of other companies by appraiser B. Also, let D = X, - 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 be the appraisal value of each apartment in the sample by appraiser B. The measurements and » are in thousands of euros and are given below. Let d = x, - 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 bigger than the mean estimation of the appraisal values of apartments by appraiser B?
