ou are conducting a study testing whether a childs 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	115
63	109
59	99
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?

24.73

59.56

52.81

59.70

43.73

What is the slope (beta) of the regression line?

1.44

1.52

1.61

0.81

1.16

The regression model predicts that a 3-year-old child (36 months) would be approximately tall.
