A company thatbuilds apartment buildings in Athens considers two appraisers, A andB, who give an estimate of the sale price of their apartments. Thesales department of the company has observed that in most casesappraiser A gives smaller value estimates of their apartments. Thecompany would like to know if this is true for estimated values ofapartments of other companies. Let be the appraisal value of anapartment of other companies by appraiser A. Let *: be the appraisalvalue of an apartment of other companies by appraiser B. Also, letD = X, - X1. The company selected a random sample of apartments ofother companies. Let be the appraisal value of each apartment in thesample by appraiser A. Let be the appraisal value of each apartmentin the sample by appraiser B. The measurements and » are inthousands of euros and are given below. Let d = x, - x. At the 5% levelof significance, do these data provide enough evidence to concludethat the mean estimation of the appraisal values of apartments byappraiser A is bigger than the mean estimation of the appraisal valuesof apartments by appraiser B?apartment x |x, apartment x, X2 apartment x x21176 17419155 16437201205164 16020190 18938155 1483153 14521187 18639162|1664184|1802220721140198|1935184 17823164 16441189 1846.207 2112420420542190 184196 19825179 17443189 1898163 16226193 19844149 143180|1862720920945223 22310191 19628186|18746184 18011148 14129166 16247185|1891222021730189 18048190|18813219 21131173 17749148 14014140 14432184 17850187 18415161 16233144|139511881871618818334188 19052186 18717159 16035169 16553200 1971820321636181 18354167 1702.

Please review Section 12.2. An agent for a residential real estate company in a suburb located outside a major city has the business objective of developing more accurate estimates of the monthly rental cost for apartments. Toward the goal, the agent would like to use the size of an apartment, as defined by square footage to predict the monthly rental cost. The agent selects a sample of 8 one-bedroom apartments and the data are shown. Size (Square Feet) Monthly Rent ($) 875 1500 850 1200 900 825 1150 1500 2000 1900 750 925 1250 1800 1100 1350 Construct a scatterplot. Size is the x value and Monthly Rent is the y value.
