Slope and ylntercept Regression Line Formula _w SYbEX a: . 1'1. 2x2 [(EXFl ' Y': bX l a, Homework 12 Emblemj; For this problem we will use the data from Figure 15.1 in the textbook (Figure 15.1 Quality of Marriage and Quality of the Parent-Child Relationship): a) draw a scatterplot. You can draw the scatterplot by hand. or you can us SPSS to create it (2 points), b) draw (by hand) the regression line (2 point). c) using the regression line that you drew. if the predictor is 77. what is the predicted value of the dependent variable? (2 Points) d} What is the difference between the predicted value and the actual value of Y in the Table 15.1? (2 point) Note: you must include the scatterpiot as part of your answer: if you use SPSS. you need to print it, draw the regression line by hand, and submit a copy (pd. \"u\" 25 80 14 98 33 50 28 82 20 90 ZX= EY= EX2= ZXY= EmblemzLBelow you see a table with variable X and variable Y. a) Complete the tabie (see example on slides for Chapter 16) (4 point), b) What is the regression line formula (show all your work) (4 points); 0) if the predictor is 65 what is the predicted value of the independent variable using your regression tine formula (show your work)? (2 point) Note: For Problem 2, you MUST use all the formulas from Chapter 16. if any other forms of the formula is used, you will not receive credit for the problem. Pmbiem 3: Give the regression line formula Y' = 3 + 0.9x, what is the predicted value 0") if the predictor is 14? What is the predicted value (Y'), if the predictor is 6? (2 point)
