Back to work!

Onto the new unit....sampling distributions! For future reference, the chapter 18 powerpoint is uploaded under our classroom resources...

Work hard on this stuff! The year is going to move more and more quickly over the next few months....make sure you're on top of your game in class, and that you come get help as soon as you need it!

For tonight, please answer questions 1 and 2 on our handout (provided in class) based on the applet below. If you lost the paper, the two questions are below:

Here's the link to the applet:   http://www.rossmanchance.com/applets/         (choose Reese's pieces)

1. Describe/outline the process shown in the applets to define a sampling distribution for sample proportions.  WRITE YOUR ANSWER USING COMPLETE SENTENCES. (2 points)

      2. After exploring the sampling distribution for proportions, define the model—shape, mean and standard deviation. WRITE YOUR ANSWER USING A COMPLETE SENTENCE. (1 point)

     I'd recommend the following sentence for #2: The sampling distribution for proportions is _______ with a mean/center of ________________ and a standard deviation of ___________.

If you'd like to get ahead, tomorrow we'll look at this applet:
