Cоnsider the cоde snippet belоw: import pаndаs аs pddata = { "Species": ["Oak", "Pine", "Oak", "Maple"], "Height": [18.2, 22.5, None, 16.8], "Location": ["North", "South", "North", "West"]}trees = pd.DataFrame(data)print(trees.shape)print(trees["Height"].isna().sum()) Answer the following: a. How many rows and columns are in the DataFrame? b. What does trees.shape return? c. What does isna() identify? d. What value is displayed by the second print() statement? e. Which variables are categorical, and which variable is numerical? f. Why should the missing height be investigated before performing statistical analysis?
