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 63 109 59 99 53 101 44 106 40 94 Perform regression of height (dependent variable) on age (independent variable). What is the Y-intercept of the regression line? O 43.73 O 59.56 O 60.46 O 73.73 O 68.60 What is the slope (beta) of the regression line? O 0.63 O 1.16 92.40 cm O 1.44 99.41 cm 111.18 cm O 0.52 96.53 cm O 0.75 98.73 cm The regression model predicts that a 4-year-old child (48 months) would be approximately tall
