(D) Caicuiate the sampie correiation coemcient r. 1097.7 10 1077.9 r= -0.974 (Round to three decimal places as needed.) 15 1057.1 20 1037.8 (c) Describe the type of correlation, if any, and interpret the correlation in the context of the data. 1015.9 25 30 996.9 There is a strong negative linear correlation. 970.1 35 40 967.6 Interpret the correlation. Choose the correct answer below. 45 967.6 50 967.6 O A. As altitude increases, speeds of sound tend to increase. O B. Higher altitudes cause increases in speeds of sound. C. As altitude increases, speeds of sound tend to decrease. O D. Based on the correlation, there does not appear to be a linear relationship between altitude and speed of sound. Done Print O E. Based on the correlation, there does not appear to be any relationship between altitude and speed of sound. OF. Higher altitudes cause decreases in speeds of sound. (d) Use the table of critical values for the Pearson correlation coefficient to make a conclusion about the correlation coefficient. Let a = 0.01 V between altitude and speed of sound.
