Quiz 5:

Done in e-Learning, covers material from Sampling Distributions

Open  Monday 1:00 pm - Thursday  11:59 pm

Quiz is worth 6 points, you have 3 chances and the highest score counts.

NOTE: One of the question sets has as potential answers things like mu, sigma, PART, sqrt(p(1-p)/n). The word PART is a mistake - some weird auto-correct function of e-learning I can't figure out how to fix right now. Whenever you see the word PART it should be the symbol "p" instead.
Because of this error the quiz will be open until Friday right before midnight and everyone has 4 chances at the quiz.

NOTES:

·      These grades already include the 1 point for bubbling things correctly.  If you did NOT get that point there will be a comment for you in e-Learning when you click on Exam 1.

·      To make sure your grade was computed correctly carefully go over your exam and count the number of correct answers out of 33. Exam grades = (#correct)x3 +1

Example:  3 questions wrong: (30x3) + 1 = 91  OR (99-9) +1 = 91   BUT NOT (100-9) +1 = 92

·      If you have questions about the answer key, please stop by the Tutoring Room or office hours to discuss them in person.

General Information

 

Course Structure:  Lectures and Labs

 

Labs – attendance required, once a week in CBD 220

·        Lab attendance is required for all students, according to the section they are registered for.  When you register for this course, please pick the lab section that is most convenient for you.

·        Labs meet once a week with a TA in CBD 220 (half a block North of University Avenue, across from Library West).

·        If you are registered for the Web lectures then the only thing that will appear on your schedule is the Lab, but everyone is welcome to attend the live class anyway.

·        The first week of classes, the TA’s will be in lab only to provide information about the course.  If you read all the information on this page and the syllabus and watch the first online lecture, you do not need to attend lab the first week.

Lectures – everyone can watch either live or online

·        Attending Live Lectures will be taught MWF 6th period in Norman 137 (350 seats).  You may also attend the taping during MWF 5th period in Norman G520 (25 seats).  Everyone is welcome to attend the live lectures, even those who are registered for a Web class.  However, once the classrooms are full, no other students will be allowed for safety reasons.

·        Watching Online Lectures: the 5th period lectures will be videotaped and available to view online as streaming video the same day they are taught, usually around 1 pm.  Everyone can watch the online lectures, even those registered for the live section of the course.

·        Link for Online Lectures is posted in the course website in e-Learning.  For the first week of the semester it will also appear on this announcement page, but after Drop/Add is over all the course content will be moved to e-Learning, and only the Announcements will appear here.
