Last week we had a very easy homework. No coding was necessary. Just plain English. This week we will continue the same approach, with more systems to analyze. Also, we will give better structure to your report.

One problem with the last homework was that many reports lacked any structure. They did not had title, the author name was at the end, phrases were incomplete, and in general they did not looked professional. This is not good, given that many of you will become professionals in a couple of months. At the university level and beyond, your work should be clean and clear. This can be done in email, in Word, or any other system.

To help you do a good-quality report, this time we will use a file in Markdown format. Unlike Word, Markdown format encourages you to use good structure and produce a better-looking document. You must only submit the file with extension .Rmd. No Word, no PDF, no HTML.

• Please use this template for Homework 9
• Write in the header your name, student number, and date.
• You do not need to write any code.
• The file must have the correct structure: header, sections, subsections, paragraphs separated by empty lines.
• Always write a “space” after dots and commas. Never before.
• The file should produce a correct output when you knit it.
• This is really super easy. You just need to get used.
