Import the numpy package as np, so that you can refer to numpy with np. Use np.array() to create a numpy array from baseball. Name this array np_baseball. Print out the type of np_baseball to check that you got it right. @hint. import numpy as np will do the trick. Now, you have to use np.fun_name() whenever you want to use a numpy function.
