Homework 4
Instructions
Upload this homework into the homework vaults in the IS no later than on 12/4 at 23.59.
The homework submitted after this date can be evaluated only if you have an excuse in the
IS for at least 3 working days in the week between the given lectures and seminars (from
these five: Wed, Thu, Fri, Mon, Tue) and the teacher has given you an alternative date when
you submit your homework. We expect that you write the homework on your own. Should
your answers resemble with the answers in someone else’s homework, we might deduct
points from your score. We appreciate the effort and thorough thinking (whether your
answers make sense, whether you have supported all your claims by careful argumentation,
whether your answers are informed by data). Try to formulate ideas as concisely as possible.
Certainly do not add any "dummy text" just in order to get closer to the maximum extent.
The final document can be inserted into the System in all standard formats (doc, docx, odt,
pdf, ...). Print your homework and take it to the seminar on 8/4. Title the document
Homework 4 (your name and surname will be added to the name of the document
