Homework!

Periods C and E should complete the following. Remember, this is worth double, and will be collected--so do it on separate paper!

Page 566: 2,4,17,19,20,32

As for Period F, complete the same page, but only the four even problems.

We have 17 more class periods until the AP exam, and we still have 3 new chapters to cover, along with finishing up all this inference about means. In other words, we need absolute focus for 17 days (18 including the exam day). What we don't finish in class will end up being work for you on your own time.

Focus.

Monday!

The answer to the "z score" poll question was in fact E! Nice job! 18/20 = 90% correct!

Homework tonight: page 566: 1, 3, 5, 7, 8(abc only)

Don't forget--extra credit! Write for the school paper by Monday!

Extra Credit? I thought he wasn't giving any?

One final extra credit opportunity as the quarter comes to a close....write for the school paper! Anything you write is due on April 5th, to me, electronically. I will then forward this to Ms. Porch and Ms. Griffin (or you can give it to them if you know who they are--but I'll need a copy as well for your points).

You can write anything for the paper--it doesn't have to even be stats! For non-stat stuff, you'll get extra credit if you make it to the published paper (I can't just give away points for any weak little story--it's gotta be legit, and the editors will know what's "legit' far better than I).

Ideally, of course, you'll write about statistics. Many of you already interviewed David Bock and wrote up your findings--simply double check your writing, make it better, tighten up all the loose ends, and give me a nice final copy (with no swears, Meredith!) and you'll get points for stuff you already did!

The same goes to those of you who wrote about Saturday sessions or our general extra-curricular statistics stuff. However, many people gave me sloppy, quickly (pathetically) done papers. Make them better! They need to by typed and electronic!

Let's make the school paper awesome! And take the credit! :)

Homework!

Don't forget your AP problem is due Monday!

Also, finish up page 544: 11, 17, 33...but I'm pretty sure you should already have 11 done :)

3/24/10

Hey guys, class was just going over homework and note taking. We're pretty much finished with ch 23.

Homework for tonight: Quiz C .. it's just like what we did in class.

Take your test BY friday.. if you haven't already..

MAKE UP WORK DUE FRIDAY!!!


=)

Note Taking Tuesday

Hey guys!
I think everyone was back in class today.. class consisted of ch 23 note taking.

Tonight's hw: Page 541 #1, 5, 7, 9, 11.

*If you didn't take your test on Friday, come in ASAP (and/or sign in) and get it done by THIS Friday.

==>Again, ALL MAKE UP WORK should due FRIDAY as well. Do it.

"A goal without a plan is just a wish."

[: <3

Mondays are always fun when class is half full!

Greetings! =)

Hope you guys on your field trip(s) had fun.. but we had even more fun, learning about new stuff like Gosset's t and degrees of freedom. There were like 12 students in class today, it was awesome! =] .. but we still have homework.
It's to read chapter 23! ..perhaps there will be a reading quiz.. maybe.


*IMPORTANT*
-If you have ANY late work to hand in... ALL DUE FRIDAY!! No excuses.


-today's quote: "an optimist will tell you the glass is half-full; the pessimist will tell you it's half-empty; and the engineer will tell you the glass is twice the size it needs to be"
hehe =)

:) [: =D

Take Home Test Due Monday!

Yoooo! Can you tell when it's actually me posting vs. Zaiba? If not, this is me.

I'm currently posting as I gaze out into the sea of students diligently answering test questions...I'm hoping, and confident (I am 90% confident, to be precise), that we can destroy this test as a class. I'm hoping that after we enter our grades (using clickers) on Monday that the test is literally blown to smithereens because we did so well. I'm not cleaning up all the little shreds of the blown up test though.

Thanks to all of you who gave me food today, even if you were just trying to get some extra points.

DON'T FORGET YOUR TAKE HOME TEST DUE MONDAY! GET AN A! EMAIL ME IF YOU HAVE A QUESTION!

I think I'll periodically be posting my email responses to questions on the blog, so keep checking...you might find some valuable information.

And last, but certainly not least....NEW STUFF MONDAY! Woop woop! I know you're all equally excited as I. I don't think it'll be too difficult, given what we already know about inference.

The end is literally near. Only 5-6ish weeks before you guys go get your Stand and Deliver on and ace the AP exam.

Have a great weekend!

Test tmrw!!

Big test tomorrow!!! Study study study!!!!
Multiple choice part tmrw!
& Opened ended for take home over the weekend.
^Correction to the take home by the way: it should say "refer to your test in part (c) NOT (e).

After school review today.. stop it yo :)

=]

Happy St Patrick's Day!!

Greetings fellow statisticians! :) and in the spirit of today's holiday.. greeen!! =D

Class consisted of review and going over some AP problems.

--> Homework for tonight: AP problem given at the beginning of class; a through d and remember to add in e: which is to construct a 95% confidence interval and interpret it yo :)

*TEST FRIDAY!! STUDY!!! -multiple choice in class and open ended over the weekend.

^Review for that tomorrow AFTER school.. stop in.

96% Confidence Interval

My bad guys...on the homework tonight you can't just use the table to find our critical value (z star) for 96%. We'll have to use inverse norm (invnorm() on our calculator. Go to 2nd --> VARS to see the distribution menu and select invnorm. Then, think about the percent of data that lies to the left of our confidence interval (96%) (draw a Normal model if you're not sure). Enter this value (as a decimal) into invnorm and it'll give us the negative z-star (just make it positive!)

Monday back! :)

Hey guys, hope everyone had a good weekend minus 1 hour =(

Homework for tonight: AP Problem.. due tomorrow.. do it.

STUDY STUDY STUDY for the test FRIDAY!!! :]


Reviews every Thursday! show up.. just sayin' ;)
*no more Monday + Wednesdays after school. Mr Carofano will be teaching a SAT prep class so if you want one-on-one help.. SIGN UP/make an appointment. Sheets will be posted.


:) <3 [:

Some help on those AP problems...

I don't know about losing one hour of sleep today....stupid clock changes.

I just sent an email response to a good question, relating to problems 1c and number 2; figured I'd throw that bad boy up here for anyone in need.

Alright, let's see how well we can figure this out via email...

First off, letter C...so here's the scenario--someone comes in to have their blood tested. What can happen? The test can be positive or negative. If it's positive, then the person will undergo two more tests; if one of these two tests is positive, the blood sample will receive more expensive and accurate testing.

So our job is to translate this situation to "And" and "Or." So the first sample has to be positive; then, we can have a few situations.

If the first test is negative, there's no more testing involved so we don't care about this situation.

POSITIVE and NEGATIVE and POSITIVE--What happens?
POSITIVE and NEGATIVE and NEGATIVE
POSITIVE and POSITIVE -- Remember, once one of the additional two tests is positive, we're onto the more expensive stuff. So the third won't matter in this case.

Now you just need to find the probability we have a positive or negative test based on all of the information given, and decide which of the scenarios above answer our question.

Onto number 2:

This question first asks about expected value and variance when combining random variables. This is chapter 16 in our book, and there's an example on page 377 which is similar to this, but instead of "M - W" the book is an example of addition.

For (a), you should be able to figure out how to find the expected value and standard deviation after looking at the example. Part (b) asks you to use a Normal approximation based on your answers to (a) to find a probability, so you'll need z-scores (you got that!). The trick is to think--if the woman is taller than the mean, what "kinds" of answers would we get by doing M - W? Then, find the probability of the answer to that question.

I hope this helped...good luck!

Happy Friday!!

No Saturday Session this weekend lol..

Assignments due Monday:

• AP Problems!!!!
• Read Chapter 22.. take notes..perhaps there will be a reading quiz.. maybe
