Homework: Section 10.1 Homework Question 6, 10.1.11 HW Score: 62.5%, 5 of 8 points Part 4 of 6 O Points: 0 of 1 Save Refer to the accompanying scatterplot. a. Examine the pattern of all 10 points and subjectively determine whether there appears to be a strong correlation between x and y. b. Find the value of the correlation coefficient r A and determine whether there is a linear correlation, c. Remove the point with coordinates (9,9) and find the correlation coefficient r and determine whether there is a linear correlation. d. What do you conclude about the 10- possible effect from a single pair of values? Click here to view a table of critical values for the correlation coefficient. 10 - X Table of Critical Values a. Do the data points appear to have a strong linear correlation? No & Yes n 1 =.05 ur = 01 950 990 b. What is the value of the correlation coefficient for all 10 data points? UI A 878 959 r= 0.880 (Simplify your answer, Round to three decimal places as needed.) 6 811 917 7 754 875 Is there a linear correlation between x and y? Use a = 0.05. 707 834 666 798 O A. No, because the correlation coefficient is not in the critical region. 10 632 765 B. Yes, because the correlation coefficient is in the critical region. 602 735 12 576 708 O C. Yes, because the correlation coefficient is not in the critical region. 13 553 684 O D. No, because the correlation coefficient is in the critical region. 14 532 661 15 514 641 c. What is the correlation coefficient when the point (9,9) is excluded? 16 497 623 17 482 606 r= (Round to three decimal places as needed.) 18 468 590 19 456 575 20 444 561 25 396 505 Clear all Check answer Help me solve this View an example Get more help - 30 361 463
