Answer all the questions below using the available data. There are multiple ways to get some of the answers. I would suggest that you attempt to merge some data sets as needed to assist with getting answers. This will make your tasks a lot easier and your code will be cleaner.

Also, you will be creating functions to get the answers to some of these questions. This will make it much easier for you to get answers to similar questions in the future and CodeGrade will be checking your functions using different inputs.

Q$1$: Create a function called data$\_$count that takes as input the data set $($for example: sets$)$ and returns the total number of rows in the data $($as an integer$).$ Nothing else should be returned.
