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	87
50	95
63	115
59	99
53	101
44	102
40	94

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

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

59.70 73.73 65.67 58.37 60.46

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

0.52 0.68 1.16 0.40 1.44

(c) The regression model predicts that a 4-year old child (48 months) would be approximately -------------------- tall.
