Question No: 03 Consider the below data set for carrying out some data science activity. There are four columns identified by f1, f2, f3, f4, f5 ("f" means feature). In the table "NA" means "Not Available" (or missing value). Your task as a data engineer is to obtain the missing values using some imputation technique. The domain expert gave advice that f3 can be imputed using mean, f4 can be imputed using median and f5 can be imputed using mean based on the feature f2. Write the steps to be followed to obtain the missing values and re-write the dataset with the imputed values.
