Description
For #3, we are asked to "Create counts of missing values for diabetes
status and alcohol use using SQL commands." Should this be the count of missing values within the table from which the data is coming from, or should it also include a count of those who are not in all relevant tables? If the latter, what is the reference population? For example, do we want the count of those missing data out of all participants in the demographics table?

Start by reading the referenced #3 assignment and its SQL commands context, then inspect how the demographics table relates to the diabetes-status and alcohol-use data. Done means the reference population and counting scope for missing values are explicitly documented.
