Instructions

Complete the questions by adding the code under the relevant chunks.

Please submit your assignment as html file to me via email. Please call your assignment: “yourlastname_assignment1.html”. For example, I would submit something called “popescu_assignment1.html”. Please make sure that it is all in lower case.

To obtain the same look as this template, make sure that your you assignment preamble or YAML looks like below:
