Question 5 pertains to the scatterplot below of weight in pounds and height in inches. (20 points) m..'3.mt Mans, wgigm a) (2 pts.) Look at Line A and Line B on the scatter plot. One is .5} 409 ' t the regression line and one is the SD line. Which is the SD :3 , for\" line? Choose oneLine A ii) Line B i see ' J; ' ,r b) (2 pts.) The correlation (r) between height and weight is ../ "\" closest to? Choose one: i) -0.2 ii) 0.2 ' 0.5 iv) 0.95 c) (2 pts.) The average height is closest to 100 Choose one: i) 60 .67 iii) 72 iv) 148 or MM" : d) (2 pts.) The largest prediction error is 85 & the smallest is 77r7 7 777' 7' . 7 7 '7 r "77 . -61. What is the average all the prediction errors (residuals)? so 60 70 80 90 Height _L Fill in the above blank with a number. i) (2 pts.) The SD of the prediction errors (RMSE) is 30 lbs., so your prediction for weight +/- 30 lbs. will be right about 68 % of the time and your prediction for weight +/- 60 lbs. will be right about 95 % of the time. Fill in the blanks with numbers. Ipt for each blank accept 68.27 + 95.45 j) (2 pts.) Which of the following statements are true about the scatter plot above? Choose one: i) All points on the SD line have positive prediction errors. ii) All points on the SD line have negative prediction errors. iii) Points on the SD line with above average X values have positive prediction errors and points on the SD line with below average X values have negative prediction errors
