Median weight of baby giris (in pounds)

Expert Solution

Part (a)

Average Growth Rate= $\frac{C h a n g e i n w e i g h t}{T i m e D u r a t i o n}$

Hence, Average growth rate of girl in her first 12 months= $\frac{C h a n g e i n w e i g h t}{T i m e D u r a t i o n} = \frac{20 - 6}{12} = \frac{14}{12} = 1.166 \approx 1.2 l b / m o n t h (C l o s e s t E s t i m a t e)$ (From the Graph)

Hence, A. (1.2 lb/month ) is the correct option.
