include your name and student ID in the author section above. You are required to use Knit render

Assignments not in HTML format will not be accepted. The use of codes not demonstrated or
utilized in class will result in a reduction of the score for that question. Additionally, the incorrect
application of statistical analyses or tests will lead to a deduction of points for the related question.
Furthermore, any attempt at plagiarism will result in an automatic grade of zero for the homework.
Best of luck.
