Hey, so today in math Mr. Max told us that the answer to the ballpark question was in the range of about $80000.00.

He went into excel and showed use how we could see our answers and the formulas that you used to get those answers.

Heres how you do it:

STEP 1 --> press and hold control button (ctrl)

STEP 2 --> press the tilde button (~)

Here are the notes that we did today.

Here is a link that may help you when your using the TVM Solver.

Hello everyone,

At the beginning of class, Mr. Max checked our homework. We were assigned to do question A from Assignment 2, of the Design and Measurement package.

Here is the answer to the question:

Mr. Max assigned us another question to do either in groups of 4 or by yourself if you prefer. He assigned question #3 (ballpark question).

Here are some hints he gave us:

Today Mr. Max continued teaching us about Design and Measurement. He finished showing us how to do the fish tank question from one of the old exams.

He recommended that we use Excel to solve the last part of the question

We then went over the homework we were assigned last night.

* Just a reminder Gst is going down to 5% on January 1st

We started off the class with Mr. Max handing back our multiple choice from our statistics test. Then he went over what we've done and what we have left in the course and we discussed how we're going to finish the course and the provincial standards test. We started on design and measurement and did an inquiry task about an aquarium from a past exam. Here's the screens

Today we corrected the two questions which we assigned on Monday's class regarding confidence intervals.

Then Mr. Max went over the relationship between the size of the confidence interal and the level of confidence. This picture represents this.

For this class we were told to finish our formula sheets and to study for our test which is on THURSDAY. Friday is a holiday(for students).

Notes from November 19th

We covered lots of material in class today so here are the notes for anyone who's having trouble. Also, we had the two questions on the handout for homework, Mr. Max said he would be doing a homework check tomorrow so don't forget.

Today's class was quite interesting. Mr.Max went way off topic (as usual). Some topics of discussion included his love for quarter pounders and cheese, maggots, force fed ducks, and of course good old butterball turkeys. Nevertheless there was SOME math done.

• There a homework check of questions 1-12 from the binomial disribution booklet



• Max corrected them for us.. answers are below

He also showed us a binomial distribution applet on the ron blond site that you can use instead of your calculator. here's the link: http://www.ronblond.com/M12/Bin.APPLET/index.html

Binomial Distribution

Binomial Distribution

Hello Crew

For today we have a work period and we have to be done 1-12 for tomorrow ( friday ) on Binomial Distribution in the booklet that Mr Max gave us.

If you want the probability of a specific number of successes in the number of trials specified, push 2nd VARS then go down to zero and select binompdf. To use this program put in number of trials, success, number of successes required.

Notes from October 25th

Hey these notes have been a long time coming. Mr. Max's computer wasn't working at the time so I couldn't post them, but here they are..


























Here are the couple examples we did that class

This is a little chart that should help us to determine when to use the triangle method and the parallelogram method.

Sorry it took so long to get the notes up, hopefully they are still helpful.

Thursday Nov 15th

Hey crew

Today is a work period and we have to learn Binomial Distribution by our selves. For Friday (tomorrow) we have to be done the questions 1-12 on the last page of the binomial distribution booklet.

To figure out questions like " when you flip a coin 5 times what is the chance that you get tales twice" use 2nd Vars, 0 to access Binomial Probability Disrtibution Function. After that you need to put in the following information in this order, number of tries, possibility of success, number of success, number of success required.

To use Cumulative Probability up to and including a specific number of successes in the number of trials specified, you need to use 2nd VARS A to access the Binomial Cumulative Distibution Function.

To fill in the brackets you must use this order for Cumulative Probability. ( Number of trials in the experiment, P(success), number of cumulative successes required ).

Hello everyone!

Today the Boss went over the questions we were assigned to do, it was very quiet, great for learning. He showed us how to do the questions on the calculator using normalcdf(low,high,mean,sd) and invNorm(%,mean,sd), here are pictures of what he did:

These are the question answers that we were supposed to do, I hope this post may help you in the future. Thankyou

First thing we did in class was we went over the question that was due for today. The question had to do with picking out 480 gifted out of 48000 students by analyzing their test scores. We had to decide at which test score would we cut off the gifted from the normal kids. The mean being 100 and the SD being 15.

Also we were assighned question 12 for the people who didnt do the homework and question 18 and the first 5 questions of the multiple choice.

nov 12th

The class started off with Mr.Max doing some things with grouping data and for an example he used the years of cars. He gave us three ways to do normal distribution. The first way was using NORMALCDF in our calculator...2nd vars 2..NORMALCDF(low,high,mean S.D). Then we used an excel spreadsheet and the ron blond website.http://www.ronblond.com/M12/norm.big.APPLET/index.html.

Hey!!
On Friday Mr. Maksymchuk went over some questions on our "review" paper, which took all class, hence there was no new notes or homework!!

Here are a few websites that might help you out in this unit:

http://www.shodor.org/UNChem/math/stats/index.html
"Standard deviation is a particularly useful tool, perhaps not one that the professor necessarily will require you to calculate, but one that is useful to you in helping you judge the "spread-outness" of your data."
-->This is off of the above website. I thought that I would paste it in here to show that other people do in fact, talk like Mr. Maksymchuk. (Note the bold word and the quotations).

http://www.childrensmercy.org/stats/definitions/stdev.htm

Hey! Today we started off doing mental math. He then talked about what he thought of our projects, and apparently he doesnt enjoy reading them. Remember that. Dont ever write "I hope you enjoyed reading this!". Next he went over the questions, 7 and 17, which were assigned on tuesday. He was going to do a homework check but the class talked him out of it.

Also Mr. Max figures our class average on the provincial exam will be about 58%.

Today all or most of the computers internet connections did not work properly, and there was no rsfiles drive either, so the notes will be posted in a bit.

Nov. 7th/07

Hey! Mr. Max wasn't here today so we were suppose to either work on our Statistics review questions (#7 and #17) or work on our Vector Project, which is DUE TODAY AT 3:40!!!!!!!!!!!!!!!!!!

Hello fellow classmates. Yesterday we kicked off class with a mental math and then continued on with our lesson on standard deviation and normal distribution. Here are the notes.







The next thing we will be working on is Z scores.

Z-scores are means of answering the question "how many standard deviations away from the mean is this observation?'' A positive Z-score indicates that the observation is greater than the mean and a negative Z-score indicates that the observation is less than the mean.

Just a reminder that projects are due at 3:40 today.

Hope everyone has a sensational day.
