# A particular ranking system determines the cost of living in the most expensive cities in the world.

A feature ranking scheme determines the require of aid in the most extravagant cities in the earth as an abjuration. This abjuration scales city X as 100 and expresses the require of aid in other cities as a percentage of the city X require. For pattern, in 2007, the require of aid abjuration in city Y was 130.1, which media that it was 30% remarkable than city X. The obligatory scatterplot shows the abjuration for 2007 plotted opposite the 2006 abjuration for 15 cities. Total calibre a through e adown. Click the icon to sentiment the facts board and scatterplot. a) Describe the company betwixt the require of aid indices in 2007 and 2006. Choose the improve tally adown. O O A. The company betwixt the require of aid indices in 2007 and 2006 is definitive, direct, and unconvincing C. There is no company betwixt the require of aid indices in 2007 and 2006. O E. The company betwixt the require of aid indices in 2007 and 2006 is definitive, tortuous, and secure. O B. The company betwixt the require of aid indices in 2007 and 2006 is disclaiming, direct, and secure. D. The company betwixt the require of aid indices in 2007 and 2006 is definitive, direct, and secure. OF. The company betwixt the require of aid indices in 2007 and 2006 is disclaiming, direct, and unconvincing. b) The R2 for the return equation is 0.81. Interpret the prize of R2. Select the improve dainty adown and increase in the tally box to total your dainty. (Type an integer or a decimal.) O A The prize of R2 = % indicates the percentage of the variability in require of aid in 2007 that cannot be explained by variability in require of aid in 2006. OB. The prize of R2 = % indicates the percentage of the variability in require of aid in 2006 that cannot be explained by variability in require of aid in 2007. C C. The prize of R2 = 81 % indicates the percentage of the variability in require of aid in 2007 that can be explained by variability in require of aid in 2006. O D . The prize of R2 = % indicates the percentage of the variability in require of aid in 2006 that can be explained by variability in require of aid in 2007. i Facts Board and Scatterplot c) Invent the apposition. The apposition coefficient is 0.900 (Round to three decimal situates as needed.) 140-1 d) Using the facts supposing, invent the smallest squares fit of the 2007 abjuration to the 2006 abjuration. 2007 Abjuration = 12.709 +0.930) x 2006 Abjuration (Round to three decimal situates as needed.) Abjuration 2007 e) Predict the 2007 require of aid abjuration of city 2 and invent its residual.
