CP Statistics Homework

Each class I will post homework that is due for the next day. If for some reason homework is not posted, THAT DOES NOT MEAN you do not have homework! You need to take the initiative to email or message me in the Remind App that I have not posted homework yet. Also, as covered in the syllabus, homework is due and will only be accepted the class after which the assignment was given, and only during the period I am checking for homework. If you are tardy or absent you must show me your homework upon return to class, and that homework will only be accepted the first day you have returned to class. You must take the initiative to bring your homework to me if you have tardy or absent.
