Exercise 8: rubric questions order, k-values visualization requirement.

[Alex Aushev]

The tasks in the assignment description and rubric questions have different order, which is confusing. Right now:
Q4 -- corresponds to task 2;
Q5 -- task 3;
Q6 -- task 5;
Q7 -- task 2 (and the "k-values should be visualized or tabulated" part from the rubric should probably be in the task description and not in the "Hint" section, since it seems like a requirement);
Q8 -- task 4;

So the right order should probably be:
Q4, Q7, Q5, Q8 and Q6.
