Q1: For each known county use Work-class and Age to predict Income with the following setting: (a) Any record associated with an unknown cell in work-class should be removed from the dataset. (b) Some values in Age columns are represented as decade, e.g., 20s or 30s. You are required to clean these values by removing the s and convert it into an integer value.
