**Describe the bug**
The census dataset columns from https://archive.ics.uci.edu/ml/datasets/Census-Income+%28KDD%29 do not match with the notebook

**To reproduce**
Download the dataset from https://archive.ics.uci.edu/ml/datasets/Census-Income+%28KDD%29, add the column labels, run the notebook

**Logs**
If applicable, add logs to help explain your problem.
You may also attach an `.ipynb` file to this issue if it includes relevant logs or output.

Open sagemaker_processing/scikit_learn_data_processing_and_model_evaluation/scikit_learn_data_processing_and_model_evaluation.ipynb and download the linked Census-Income (KDD) dataset with its labels. Compare the dataset columns with the notebook's expected columns, then verify the notebook runs successfully with the aligned data; the issue does not specify which side should change.
