The distance (in kilometers) and price (in dollars) for one-way airline tickets from San Francisco to several cities are shown in the accompanying table. Complete parts a through d below. Click the icon to view the data on airline ticket prices. a. Find the correlation coefficient for these data using a computer or statistical calculator. Use distance as the x-variable and price as the y-variable. r=(Round to three decimal places as needed.) b. Recalculate the correlation coefficient for these data using price as the x-variable and distance as the y-variable. What effect does this have on the correlation coefficient? Select the correct choice below and fill in the answer box to complete your choice. X (Round to three decimal places as needed.) OA. The correlation coefficient is r=. The correlation coefficient decreases when the order of the variables is changed. OB. The correlation coefficient is r= The correlation coefficient remains the same when the order of the variables is changed. OC. The correlation coefficient is r The correlation coefficient increases when the order of the variables is changed.
