In a study to investigate growth rates of children, you collect data on the height (in inches), age (in months), and sex (0 = male, 1 = female) of each child in your sample. You fit an ANCOVA model to predict height based on age and sex. The fitted model is given as follows

(Height) = 32.96 + 0.18Age + 7.73Sex - 0.06AgeSex

1.If you were to visualize this model, what would you see?

a.One regression line

b.Two regression lines with the same slope but different intercepts

c.Two regression lines with different slopes and different intercepts

d.It is impossible to tell

2.Interpret the coefficient for(-0.06) in context.
