Reassessment Tomorrow! Complete the form if you plan on reassessing. Make sure you Re-learn

Grades (boo!) - if you'd like to "improve your grade" for the 3rd marking period, make sure you get your Unit IV projects posted by next Friday

What we're doing
1. Who has made appropriate conclusions - yesterday's P-values and rejection decisions
2. Formalization - need one "note-taker" for each skill listed below (please don't make me randomly generate)

3. Unit IV Projects
4. Wiki Edits - add CONTENT not just organization to the class wiki. Look at each skill page and decide if there is enough there.

Monday March 21, 2011

1. Binomial vs Normal Distribution
2. Writing a null and alternative hypothesis (Skill 20.1)
3. Conditions for the Normal model (Skill 20.2)
4. Determining probability of your sample proportion (Skill 20.3)

3. So what is the true proportion?

## Tuesday March 22, 2011

Choose one of the four options below.1. Re-learn some stuff from Probability Distributions

- Skill 17.1 - diff between binomial and geometric - <this page needs to be made, so you can make it if you wish>
- Skill 17.2 - geometric probability
- Skill 17.3 - binomial probability
- Assessment - Geometric and Binomial Probability - try this if you think you're good

2. Re-learn some things from a previous chapter- Come up with a plan to get smarter
- Get smarter - Learning Resources

3. Unit IV Projects4. Wiki Edits - add CONTENT not just organization to the class wiki. Look at each skill page and decide if there is enough there.

EVERYONE1. Brackets - Unit V Project

2. Hypothesis Testing Intro - Tack Tossing (Skill 20.1)

OPTION OF 1 (WHEN FINISHED ABOVE TASKS)3. Projects

4.Geometric and Binomial Probability Assessment (look at it and see what you can do)

## Wednesday March 16, 2011

1. Binomial vs. Normal Probability calculation (Skill 17.3)- Determine both binomial probability and normal probability
- n = 6, p = 0.3...P(X<=2)
- n=30, p = 0.3...P(X<=12)
- n = 250, p = 0.3...P(X<=70)

2. For each model given, convert to a model of sample proportions (Skill 16.3)- What's the new mean?
- What's the new standard deviation?

3. Is the normal model appropriate to use to calculate probability?- n = 10, p = 0.6
- n = 25, p = 0.95
- n = 500, p = 0.1
- n = 25, p = 0.5
- n = 30, p = 0.007

Skill 17.3: Binomial Distributions1. Create a new "Presentation" in Google Docs

- PrntScrn, Paste in Paint, save as .jpeg, insert image into Google Presentation
- Presentation - Binomial Distributions - Google Presentation
- Work in Google Docs "privately"
- When your slide is complete, go into the presentation link above, choose "Insert"->"Import Slides"
- Find your slide and import it into the presentation

2. Reflect on the presentation - what are we seeing? (shape, center, spread)3. Free Throw Shooters (on board)- You're an 80% free throw shooter - shoot 5 shots, how many do you make?
- 10 shots?
- 20 shots?
- 50 shots?

(Senior Skip Day)16.3-16.4 Check-In

Skill 17.3: Binomial Distributions

## Friday March 4, 2011

ReassessmentCheck answers to 16.1-16.4 Assessment

- Discuss your answers and questions you have with some people sitting next to you
- In your own Google Doc, make corrections, and also comment on things you may not understand
- Wrap-up Discussion With Class - VARIANCES ADD!!!!
- Helpful Hint: If you calculate the standard deviation of a random variable, square it so that you'll also calculate the variance
- VARIANCES ADD...ALWAYS!
