WeBWorK UPDATE: Normal Distribution questions

Posted on by

Hi everyone,

Regarding the normal distribution questions in WeBWorK (the ones using the table handed out in class), it is important to know the following:

WeBWorK expects the answer to be a decimal (between 0 and 1), rather than a percent (between 0 and 100).  Therefore, you MUST convert the percent given in the table into a decimal before entering your answer (move the decimal point two spaces to the left).

My apologies for any confusion this has caused!

WeBWorK Update – a few notes

Heads up guys – If you have not entered an email address into WeBWorK, I CANNOT RESPOND to your questions sent from within the WeBWorK system – I get an email with your question, but have no way to reply.  You can enter your email address by logging in to WeBWorK and selecting “Password/Email” from the menu on the left.  Thanks!

Some things to be aware of:

1.  Several students have run into trouble in Assignment #3 entering scientific notation, when the exponent is negative — there is an error indicating that parentheses are not allowed.  If this happens to you, try entering your answer without parentheses, like this:

2.5×10^-5

2.  In Assignment 4, we did not have a chance to cover problems number 4 and 5.  You are NOT responsible for these problems this week – you will be asked to complete them next week.

Let me know if you have any questions,

Mr. Reitz

Getting Started with WeBWorK

WeBWorK is accessible from on and off campus (anywhere you have access to the internet).  Your first 4 assignments are due on Monday, June 10th, at midnight, and will cover the material from the first week of the course.  Here’s what you have to do:

Assignment.  To get started on your first assignment, you must complete the following three steps.

Step 1.  Log in to WeBWorK here:  http://mathww.citytech.cuny.edu/webwork2/MAT1180-Reitz/.  I have created Usernames and Passwords for each student registered for my class.

Username.  Your username for WeBWorK consists of your first initial plus your last name, all lowercase (for example, John Smith would have username ‘jsmith’).

Password.  Your temporary password is the same as your username (if your username is ‘jsmith’, your password is currently ‘jsmith’).

Step 2.  Change your password and update your email address.  To do this, select “Password/Email” from the main menu on the left.  Use whatever email address you like (I suggest using one that you check often).

Step 3.  Complete the first assignment, titled Assignment1-WelcomeAndGettingStarted, by clicking on it in the main screen.

If you have any trouble – either with logging in, or with completing the assignment, post a comment here or send me an email and I will get back to you.

WeBWorK Tips:

  1. Click on a problem to see the details (the list of problems appears in the menu on the left).  Enter an answer and hit “Submit Answers”.  Don’t worry, if you get it wrong you can try it again.
  2. If the answer is a number:  you can enter it either as a decimal, like 3.57143 (round your answer), or as an exact answer, like 25/7.
  3. You can work on the problems in any order you wish.  You can do some problems now, and come back and do the rest another day (your work will be saved, as long as you submit your answers).
  4. If you want to print out a copy of the assignment, click on the assignment name in the main menu on the left, and then click the link in the main screen area that reads “Download a hardcopy of this homework set.”
