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) 34 Height (cm) 77 50 95 63 109 59 115 53 115 44 102 40 91 Perform a regression of height (dependent variable) on age (independent variable) What is the Y-Intercept of the regression line 7 O 43.73 73.73 59.56 39.07 60.46 What is the slope (beta) of the regression line? 1.16 99.41 cm 1.44 96.53 cm O 0.45 111.18 cm 1.31 92.40 cm 0.52 117.70 cm The regression model predicts that a 4-year-old child (48 months) would be approximately tall
