9. TI Calculator problem set

You 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	95
63	130
59	120
53	109
44	102
40	94

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

What is the Y-intercept of the regression line?

58.37

24.73

73.73

68.60

39.07

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