Question

Consider the following table of data. Complete parts (a) through (c) below. x 1 2 3 4 y 2.00 2.00 2.00 2.60 a. Calculate the correlation coefficient. r = (Type an integer or decimal rounded to four decimal places as needed.) b. Sketch a graph of the data. Choose the correct answer below. c. Based on how closely the data fits a straight line, is the answer to part (a) surprising? Discuss the extent to which the correlation coefficient describes how well the data fit a horizontal line. A. It is surprising. Given how closely the data fits a line, one would expect a correlation coefficient close to 0. B. It is not surprising. Given how closely the data fits a line, one would expect a correlation coefficient close to 1 or - 1. C. It is surprising. Given how closely the data fits a line, one would expect a correlation coefficient close to 1 or - 1. D. It is not surprising. Given how closely the data fits a line, one would expect a correlation coefficient close to 0.
