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	114
53	101
44	122
40	94

Perform a regression of height (dependent variable) on age (independent variable).

(a) What is the Y-intercept of the regression line?

59.56 43.73 24.73 60.46 52.81

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

0.63 0.86 0.52 1.52 1.16

(c) The regression model predicts that a 5-year old child (60 months) would be approximately -------------------- tall.
