a. The table shows the approximate distance between selected cities and the approximate cost of flights between those cities. Calculate the correlation coefficient between cost and miles. Cost Miles r =(Round to three decimal places as needed.) 190 966 398 3105 266 2009 103 431 431 2985 b. This table shows the same information, except that the distance was converted to kilometers by multiplying the numbers of miles by 1.609 and rounding to the nearest kilometer. What Cost Kilometers happens to the correlation coefficient when numbers are multiplied by a positive constant? 190 1554 (Round to three decimal places as needed.) 398 4996 266 3232 103 693 431 4803 O A. The correlation is The correlation coefficient decreases when the numbers are multiplied by a positive constant O B. The correlation is The correlation coefficient remains the same when the numbers are multiplied by a positive constant. O C. The correlation is The correlation coefficient increases when the numbers are multiplied by a positive constant
