Ag Awareness
Well hello everyone! This is my speech that I am going to a state competition in a couple weeks and Mr. Quinn talked with me and we thought it would be cool if we created questions about agriculture that the general public should know. Than ask these questions to SBHS students as well as Aromas and other high schools. Does anyone want to help me out? This way I can use my own Statistical data in my speech! If you have any questions just let me know!

Next Review Session
Stat people: I am thinking that Monday and/or Friday are the only possible times for a review session this week. Please give feedback when you read this.

Tomorrow's Agenda for Tuesday - WORK HARD
· No new homework today, but you had better work hard in class…
· First item is for students to work on Practice Exam – Open Ended Problems (Free Response #4). They can work with each other on this piece. Give them between 20-30 minutes, they will not complete it. They should be writing FULL solutions to the best of their ability on binder paper. Being noisy is OK. This will possibly be reviewed at the session tomorrow-all students are expected to attend.
· Stop them. Check solutions to AP Statistics – Class Activity. This was part of their homework. The solutions are here on a sheet and have been posted on the blog…this better be complete…collect it and tell them that I am going to grade it for credit. This should take 5 minutes at most.
· Pass out ½ sheet with graph on it. Tell that you are going to time them —give them 10 minutes to quietly work. Then have them discuss the problem. DO NOT make changes, just discuss. I want to see how they are doing without adjustments. Collect it. 25 minutes max.
· Finally, a practice multiple choice exam (18 questions). Tell them this is a bit more serious than last week’s. They may write all over this document, just make sure they circle the answers they choose. I am going to score it, NO TALKING. Give them 40-45 minutes. This has to be done, so please adjust time of other activities if you see fit. Collect it. DO NOT SHARE ANSWERS.
· Chapter 26 Homework will be collected and discussed on Thursday.
· All people are expected to attend one review session tomorrow on Wednesday – times are on the board and the web page.

Solution to Regession Homework
1. Linear increase in # graduated in the years from 1950 to 1972. Then we have a linear decrease from 1976 to 1989. Then we finish with another linear increase from 1989 to 2000. This a cyclic looking scatterplot.
2. Only going to use data from the years 1950 to 1972 to generate the equation (note: coded years as 1950 = 50): grad-hat=-592.16+15.52year. Using this equation we predict for 1969 a graduating class of 478.72.
3. Only going to use datat from 1989 to 2000 to generate the equation: grad-hat = -362.19 +8.16year. Using this equation, we predict for 2005 a graduating class of 484.61. We are hesitent to use this equation becuase 2005 is out of the range of the inputs (x's) were are using. Extrapolation is risky in regression, because we are predicting into the future.

Good Luck
Good luck to all of you for this test. This might be just a little late but I want us to do our best.
Practice Test Solutions
This is not going to work too well as I have to type them....
#11.) a.) Because n is large (over 30), skew should not be a problem. CLT is in effect here.
b.) t df=49 (235700, 3606.2)
c.) No, not unusally high as $235,700 is in the inteval
d.) keep t* = 1.676, solve for n...get n=457
#12.) t is questionable here because M2 is not normalish....anyway if we continue: a p-value of .0041 is strong evidence against the two data sets being equal. It appears the adjustments have improved the gas mileage.
#13.) a: 1 z -
b: 3 t 23
c: 2 z -
d. 5 t 14
e. 5 t 9
f. 4 t 19 (or 33.1 from technology)
#14.) a. Ho: u = 10
Ha: u > 10
b. I thought type II as this would mean that we are missing a chance to become more effecient.
c. To increase the power we can increase alpha or increase n. If we increase alpha, we run a higher risk of a tpye I error. If we increse n, it is more expensive and takes more time.
#15.) West data is skewed...we should not do a t-test. The other conditions and assumptions are OK I believe.

Unit V Test
All stats students must come in to take the unit V test at one of the following times: Friday 27th before school, 4th, 5th, 6th or after school; Saturday at 9:00am; Sunday at 10:00am.
We reviewed the pairs quiz today, the multiple choice packet and used the test as a practice tool. Naturally we ran out of time. See others to get help.

Tomorrow's Agenda
First: We work on a practice multiple choice test in groups, then check it with the solution provided.
Second: We take a pairs test so that I see what we know and what we need to review for Thursday's individual exam.
Third: If time, you guys get into your Gum Groups to figure out where you are on that project.
Try to have substitute teacher not get in the way!!!
Review Assignment: page 513 #5, 8, 13, 21

Quizzes and Tomorrow (Feb. 5)
Guys, it appears there is some frustration with the quizzes, on your part. I see gaps in your knowledge, not necessarily from lack of effort (although that may apply to some...) but rather because the concepts have not quite settled. All I can say is good thing we did not take the quiz on the day of the rally.
Tomorrow's agenda: check out the quizzes, answer some homework questions, do some practice problems, collaborate in your gum groups, and watch the last video in the series.
My dream is that it all starts to fall into place for you soon. Good night. Oh yeah, you all are supposed to post to each other WHENEVER you so choose.

Rice Demos
So, overall, I'd have to say that i enjoyed the rice demos.
Although, i am still confused as to what any of this had to do with rice...

Hypothesis Testing
Do you get the big picture? Can you describe a p-value (in your own words)? Please post answers to these essential questions.

Tuesday's upcoming class
Stats people: Let us see if we can improve the time when I am out of the classroom. I would like to cover two main things on Tuesday: an activity with dice and the second half of the notes for chapter 18. Can a I get two volunteers to lead these activites? This way I can write in the Sub plans that you (the students) will guide the lesson, and they (the sub) can relax. Then hopefully you all learn more and not get encumbered by different philosophies.
Post back tell me what you think. Then get your friends to post. Text them to post.
If (when) I get volunteers, then I can e-mail them the plans and THEY can try to make sense to the activities for the class. I'll select just a couple people and let people know. This could be a huge success if we try.

hmm
i thought there would be updates...
i got one for ya!
Under which conditions is a Normal model useful in regards to samples? (Hint: 2 conditions)
~&~
Which conditions should be present before using a Normal model? (Hint: 3 conditions)
