Statistics: Quiz Monday

As discussed in class the past few days, there will be a quiz on Monday, chapters 5.1-5.3, up to and including the Central Limit Theorem (but not including Confidence Intervals)

Statistics: Population vs Sample Means

If you are getting confused by terminology ("Mean of sample means ...") and the symbols in class I would highly recommend you take some time studying them (definitions in 5.3 and at the beginning of 5.1). It will definitely pay off in aiding your understanding. At this point, having put about a week into it, I am using them with the assumption that you are familiar and comfortable with them.



Homework is on the second slide. Essentially, we calculated some sample means and standard deviations from a known population mean and st. dev. and compared the two.

Statistics: Sampling Methods

Friday: We discussed the smapling methods on p.187 (poor sampling methods) and p.188 (good sampling methods). Homework was p.189 #1,2,3 No pictures for this day, sorry, but the notes in the book are quite good.

Monday: There was a substitute in on this day, and review questions were given for ch. 5.1 and 5.2

Statistics: Normal Distribution

Homework is q.12,15,16,17, as well as find the mean of the data we found in class.

Statistics: Mean/Median/Standard Deviation Review

Sorry for the dark pictures, I'll work on rectifying that in the future.

Homework: p.176 1-5

Matrix Multiplication

Matrix Add/Scalar Pt. 2

Matrix Addition / Scalar Mult. Pt. 1

3D Graphing

Elimination / Substitution

TEST THURS

Spend the class going over the review test; reminder that the test is on Thursday. We will be starting chapter one tomorrow.

Sinusoidal Word Problems con't

Continued work on sinusoidal word problems. We will finish this off during one period of the double tomorrow, and continue with chapter review in the second period, thus completing this chapter.

I realize these problems don't necessarily come "easy", but please don't give up on them too easily.
Believe it or not, you use "words" everyday in real life!

The key things you are trying to do here is change the word problem into a graph. Once you have gotten that far, it's just like all of the other problems we have been doing. In particular, you are looking for these values:

MAX
MIN

You need a maximum and minimum value to solve these problems. They are there in the problem, you just need to find them. Look hard. Use binoculars if you need to. Don't give up!

Here are some of the problems we solved in class. Homework was the completion of the sheet we did in class.
