From the clinical trial of an experimental growth factor drug, we got the following data, where D is the administered dosage unit and n is the total unit of neutrophil increased. From this data, can we predict n for D = 10? If yes, what should be the most likely predicted value (you need to show all the calculations)? If not, why (you need to show all the reasonings)?

D 1 2 3 4 5 6 7

n 0.5 2.5 2.0 4.0 3.5 6.0 5.5
