You are conducting a study testing whether a child's age is a good predictor of his or her height. You have collected the following data from a random sample of seven children: Age (months) Height (cm) 34 77 50 95 63 111 59 105 53 101 44 102 40 94 Perform a regression of height (dependent variable) on age (Independent variable). What is the Y-intercept of the regression line? 43.73 60.46 68.60 52.81 39.07 Perform a regression of height (dependent variable) on age (independent variable). What is the Y-Intercept of the regression line? 43.73 60.46 68.60 52.81 39.07 What is the slope (beta) of the regression line? O 1.31 O 1.16 0.45 0.63 0.92 The regression model predicts that a 3-year-old child (36 months) would be approximately 99.41 cm 96.53 cm 117.70 cm 85.91 cm 98.73 cm tall
