APPLETS DON'T RUN? Things
try, where they work...
Usually it's a Java problem: No Java installed, or Firefox thinks the version is a risk and someone's disabled it. Or Firefox is refusing to use it even if it's enabled, because it's too old.
David S. Moore textbooks have websites. Mostly we'll use the
The disk in your book (if you have one) is basically "the" website, and you can use it usually instead of going to the web. See me if you don't have one and need it.

I know we'll use these applets:

Simple Random Sample: (p. 207)
Probability For a fair coin, leave probability at .5. It accumulates tosses until you hit Reset.
Also Confidence interval
P-value of a test of significance

computer labs: if there is a folder labeled

where they work...
Usually it's a Java problem: No Java installed (I think we've got all those fixed), or Firefox thinks the version is a risk and someone's disabled it. As of Jan. 18, there's a huge flap about Java being a big risk in general (It isn't a risk from trusted Applets, and the ones I'm sending you to I trust, but Homeland Security doesn't.) Anything older than Java(TM) Platform SE 7 U11 10.11.2.21 may cause a problem on any browser. At the very least, you'll probably be explicitly asked if you want to Run the applet.
Java is on the computer and up to date? You
still have problems with Firefox (Mozilla) blocking your
applet. This link will take you to Mozilla

I don't know what other browsers are doing at this time.
Main computers--I don't know the status yet.
Macintoshes (Safari, Chrome) in Macmillan 110 may or may not be willing to run an applet.
Elsewhere, Internet Explorer doesn't seem to complain about an old Java (I think)
Library: you may be able to download and update Java directly (see "your personal computer" below)
Mac 101: Only an administrator can update Java.
What you can do (maybe): In the Firefox menu, in the Firefox menu, find Add-ons (may be under Tools menu). Then Plugins: Find the Java(TM) Platform SE 6 U31 (or 29 or whatever) plugin. It's probably been Disabled. Enable it. (Only an administrator can actually update the Java program). You'll have to close and reopen Firefox, but then the Applets should run (till someone else disables the Java) I believe all the machines have some version of Java installed. If it's been Blocked by Mozilla, see just above.
Your personal computer:
Firefox: find the menu bar, find Add-ons (may be under Tools menu). Then Plugins: Find the Java(TM) Platform SE 6 U31 (or SE 7 U 10 or whatever) plugin. If it's not there at all, you'll need to install it new. If you haven't updated in the last week, you should update it anyhow.
At the bottom of the Plug-ins list, or above it (depending on version) is "Find Updates" or "Check to see if plugins are up to date" or something like that. Choose that. You'll go to a webpage with your plugins listed and buttons to get updates.
The "Java (TM) Platform SE 6 Uxx" (or something like) button takes you to the Java website where you can download the new one. (It's V. 7 Update 11 10.11.2.21, as of today) You can also get there via http://java.com/en/download/index.jsp Click on a link to download.
On my XP machine, it asked (last April) Would you like to
this file. (Yes, Save File) Save it to the desktop or
somewhere you can find it, if it asks you . After
file, you need to run it: In the small Downloads (Firefox)
window, double-click on the file name. (Or find
the desktop and do the same.)
It will ask you if you're sure, and continue through a sequence of steps and windows. For me, it suggested the Ask toolbar add-in (which I've tried and found annoying)--uncheck the little square box in the middle of that window if you don't want it. Then continue with the installing. Eventually it will finish.
To connect it up with Firefox, close and reopen Firefox: it may prompt you to accept the new Java. If it doesn't, you should be able to go to Add-ons, Plug-ins, and enable it from there, if it didn't do it automatically.
Java is on and up to date? You may still have
