November 30 Post...24 Days 'til Christmas

Hope you all had fun on your two snow days!
Mr. Max brought Nemo Kleenexes...yay!
Mental Math...everyone's favorite thing on an unmonday Thursday
Then we looked at the wiki site...Mr. Max will check what you've done on Monday because of the snow days...so you have a few days to figure out what question you want to post...just make sure you check the site first to make sure your objective hasn't been posted yet...Also check out the posts by pbwiki so that you can play with the html codes, underlining, bolding, and boxing things...


NORMAL DISTRIBUTIONS
Calculating Percent Values Under the Normal Curve

3 ways
1. Spreadsheet Way
ex) "Chicken Moisture"

2. Calculator Way
**Today is last day for ShadeNorm...Now use normalcdf
Bring to screen normalcdf (2nd Vars, 2)
normalcdf (low real score (2), high real score (6), mean (3.8), sd (1.3))
or normalcdf (low z-score (-1.385), high z-score (1.692) )

z = x - mean z = x - mean
sd sd
= (2-3.8) = (6-3.8)
1.3 1.3
from = -1.385 to = 1.692
***Nice, neat, even, and good way without too much hassle

3. The Web Way
