1. Import the homework data excel file into R.

2. Create a new variable 'obese' that distinguishes those with a BMI of 29 or lower from those with a BMI of 30 or higher.

3. Create a new categorical variable that distinguishes between those who live in Boston and those who live in any other city. This would mean that the variable is dichotomous Boston/all other cities.

4. Upload the code that you used to do these transformations in a text file
