8. pls answer all. had to split in two screens because it was too long.

O Given are five observations for two variables, c and y. 14 1 13 7 19 15 yi 55 45 53 12 25 10 a. Choose the correct scatter diagram for these data: B 60 50 50 40 40 30 30 20 20 10 104 search O 9 2 650F 4964 AA ng.cengage.com CENGAGE | MINDTAP Q Search this course ? Exam 5 Homework X 10 20 30 40 50 60 10 20 30 40 C A-7 b. What does the scatter diagram developed in part (a) indicate about the relationship between the two variables? There appears to be a |negative linear relationship between I and y. c. Try to approximate the relationship between T and 3 by drawing a straight line through the data. Many different straight lines can be drawn to provide a linear approximation of the relationship between r and y. O d. Develop the estimated regression equation by computing the values of bo and b1 using equations: (Enter negative val figure) [(zi - I) (yi -y) b1 = bo = y - biI y = * + I ( to 2 decimals) e. Use the estimated regression equation to predict the value of y when = = 6. y = ( to 2 decimals) Hide Feedback Partially Correct
